You change the way you load the rod by changing what you feel of the rod, not the characteristic taper of the rod.
The concepts are butt-heavy vs. tip-heavy, and mass dampening.
With a butt-heavy rod (combo), your tendency is to throw tighter loops, and the opposite with a tip-heavy rod (again, combo).
The dampening idea is the more mass in the system, the less you feel from the rod itself.
The ideal set-up is going to be the lightest reel that keeps the rod from pulling you (and fatiguing your joints in torsion if it's really tip-heavy).
The nice thing about short light rods in general, is you're never going to get to this tip-heavy extreme, so you virtually can't find a reel that's too light - the lighter the reel, the more you feel from the rod.

Personally, across the board, I like just slightly tip-heavy. Balance within an inch or three so of the grip.
There will be arguments about how the balance changes with more line, etc., (which are really non arguments, because it's the same with all rods) but finding what you like for a starting point is always a good thing. Some people like a rod that reminds them to throw tight loops.

No

look at it this way.
Your senses tell you a rod seems faster if the reel is heavier, because the weight of the reel is pulling the rod to vertical.

When you get to the extreme of a long, heavy rod, too tip heavy fatigues your joints from the load of stopping and reversing the rod.
A heavier reel there literally reduces that load on your joints and helps you change the rod direction.

Really, when you think about it the perception is what makes us like or dislike any particular combo. By and large my preference is for a butt heavy feel and when i perceive that just right feel I will make better and some times longer casts. I think I agree with the others on the mechanics involved, but believe perceived fit is what counts. I don't like to fight a tool.

I'd agree with the general consensus here. Rod balance is a big thing for me, and it can definitely affect how the rod feels in your hand. But I don't think it technically changes how the rod loads. I think it affects how you work it. So, if changing the balance point with a different weight reel has a positive impact on how it works for you, it's a win.

I think a change of 1.5 ounces is where it begins to be noticeable.

Dude, that is one hell of a cast. Is that RPLX one of those two handed rods?

Here's a guy who swears all rods cast better and easier with no reel. I met him at a show, and he has some good info, but was not convinced to buy his system.

Sh!t, if I were shooting that much line, it would look like a Tiger Woods driver spraying balls 3 fairways over...

140' a seriously legit cast. I'm trying to think of a situation in my fishing where I'd need that. Perhaps on occasion for surf perch, although most are caught well within that range.

i really tend to like rods i have read other criticize as being “tip heavy”.

all of my rod/reel pairings place static balance point an inch or two beyond the front edge of the cork grip

It's a surf thing, bro.
So what happens? I hook up a 25-lb stingray that takes me a half-hour to drag on the beach while my buddies are limiting out on specs.
It's OK, I then got some specs, too.

I have that same rod and tried half a dozen reels on it. The best for me were a sage click and a galvan brookie, anything with a real drag was too heavy (4oz - too heavy, around 3oz or less - perfect). Pretty much just agreeing along with what others have said here, but with the balance point is in front of the grip I "feel" the rod load and unload better in my cast. For me this is a lot of the fun of this fiberglass rod ....
