I recently purchased a Cabelas Prime 7'3" 5 weight fiberglass rod , and I was thinking about mounting an Orvis Battenkill( Made in England by Hardy) 5/6 reel . Being that I'm new to fly fishing ( this is my first year) , I wondering am I looking to be disappointed using this combination at my local pond where I try to catch bass using poppers and sponge bugs? Also I find that I really struggle with some of the poppers I try. ( No distance) . I don't know what type of line came with the reel when I bought it. Any suggestions as to the rod and reel combo, and what type line I should use.

I agree with Jim P's suggestion about the size of the poppers. The Prime has alot of flex which makes casting flys oversized for the weight of the rod troublesome . Since you selected the Prime, I assume you like the sensitivity the rod has when playing a fish and you might not like a larger rod.
As a rule of thumb, if you follow the recommended hook size for a rod your will have a better casting experience; for a 5 wt the maximum recommended hook size is a #8; this is information available on the web.
The rod should have been sold with the correct line, likely a WF 5 wt. If you have a locale fly shop take the line to them and they will be able to access the line weight and whether the line is appropriate for the rod. You could also lawn cast without a fly and evaluate how the line is loading the rod; watching you tube videos can provide some idea of what a loaded rod should look and feel like.

To augment all of the excellent advice already given I'll add:

Regardless of what rod/line you use, keep your leader simple, short & stout when fishing poppers or any big, resistant stuff. In other words, resist the urge to use 9' 4X trout leaders.

I'm sure lots will chime in their favorite bass leaders but suffice it to say .013 is a gossamer BASS tippet in my world and 5-6' feel long is the norm of my overall leaders.

Good luck!

I think the rod is too weak for what you want to do. Cabelas is good about taking a product back. Even if you used it.

Thanks to all who chimed in , the advice is extremely helpful and I will follow up with some of the local shops to see what I do have in the reel . Just so you know I do have (2) heavier rods to use , The before mentioned Conolon-F-80 with a Ross 7wt. reel and a Cabela 8wt graphite rod with a similar 8wt Ross reel. I just like using the shorter one because the pond I cast at is real close to some adjacent condos.

Foam flies will be easier to throw than deerhair bugs. I would definitely make sure your leader is up to the task. My bass leaders are shorter, stiffer and heavier than my trout leaders. Sometimes just 4ft of 16lb mono and another 3ft of 12lb tippet. The 5wt Prime with throw a 6wt line easily. Chubby Chernobyls are a good fly to throw for bass with a 5wt rod. Just splash it down on the water . Most of all, have fun!!!

I think this is spot on. Most people never think much about the importance of leaders, especially for big bugs and streamers, where many people simply use a length of stiff mono. Then they wonder why it doesn't cast. Or why the fly smacks them in the back of the head from tailing loops.

Regardless of how you fly fish, the leader needs to properly transmit the ENERGY of your cast from the fly line to the fly. Failing to do that causes all the above mentioned problems, as well as no distance on your cast, as the bigger fly/popper/streamer won't turn over properly, because the leader doesn't transmit the proper energy to overcome the wind resistance of a big fly (or weight, for that matter).

A simple analogy is this: You throw a football all of your life. You have accuracy and distance, as well as confidence in your ability to do so. Then someone hands you a football that is 50% bigger, and slightly heavier. What happens to your accuracy and distance? Growing a longer arm would help, but a stronger arm will work, too. Why? Because you are transmitting the energy more efficiently.

I'm not a great fisherman, but I do understand leaders, as I've been making and selling furled leaders for years. I find it amazing that people will spend hundreds or even thousands of dollars on a rod, then couple it with a top of the line reel, the 'best' line, and yet use a $4.00 leader and expect good results. Hell, people spend more on leader material than leaders.

Think about it.

It depends on the rod too. Some are a lot stiffer than others. I only had one Prime rod, but sent it back. It was too soft for me and I only fish for trout.

Base your rod/line weight choice on the size of the flies/bugs/poppers to be cast, not the size of the fish to be caught. If the fish are substantially larger than typical, choose a still heavier rod/lineweight. It is vastly more efficient to cast smaller flies with an upsized rod/lineweight than to "throw" oversized flies for the rod/lineweight. It used to be this was what was really meant by "balanced" tackle--well matched. It happens that weight-balanced combos are usually the outcome as well. Even when a rod for a light line weight will "throw" oversized junk, it will lack the hooksetting guts for the hooksizes used, and it will be less responsive in mending line, taking up slack before a strike and so on because it will be "soft" relative to the bulk/weight it is being asked to deal with.

A quick comment. Another advantage to balancing the rod/leader/fly is it's puts less stress on the body.
When I was younger it didn't matter so much, but as I've aged paying attention to balance keeps me fishing.
