From talking with Mario and Mike, the 7'2" #4 Wojnicki 217P4 was designed to cast a DT4 and the McFarland 7'2" #5 was designed for a Wulff TT5. I took the two rods out for some lawn casting this morning and found both rods to be very similar in the way they cast a Supra DT4. If you do a very unscientific "waggle" test, they feel and look very similar, at least to me. That said, the McFarland blank profile looks like a normal progressive taper while the Wojnicki appears to be almost a reverse taper in the butt section with a heavier (thicker) mid and tip. I have never miced the Wojnicki so this could just be an optical illusion. The 217P4 is listed in Mario's website as a true parabolic but oddly Mike told me he didn't design my Spruce Creek 7'2" #5 as a para or even semi-para rod, but just a slower progressive. What ever they are, they are both very sweet rods with very different but beautiful cosmetics - perhaps fraternal twins.
Frog, I am assuming we both have the same rod? Didn't some folks call it the "McDriggs"? Jeff, I'll bring the 217P4 to Allenberry.
Edit: I did a search for "McDriggs" and found that Lugan commissioned Mike to build one which was indeed parabolic. It was built a few years before mine. (Mine was built in 2010.) I'm now thinking my 7'2" #5 is not the same rod as Lugan's McDriggs even though it is the same length and line weight. It certainly feels like a para rod to me but I'm not the best judge of actions so if Mike says it wasn't designed as a para rod then I guess it isn't. Still, it sure feels a lot like the Wojnicki 217P4. I would guess Frog's rod is one like Lugan's old rod ... maybe it is Lugan's rod?
Sorry to take this Wojnicki 235P5 thread off on a tangent but was just trying to relate my impressions to JASTrout and Frogmorten's posts.
