Ok got it. So do the Puma BB WInner(16x19), Estusa PB(16x19), and Estusa Provantech PB(18x20)share the same composition and feel but just with different weight? I have only used the Puma Super and winner, so those are my reference points, and why i am asking about how the Provantech PB compares in composition and feel to those. I like the composition and feel of the Puma Super.
Why didn't you like the Estusa Provantech PB? Is it because of the composition of the frame with too much fiberglass or the 18x20 string pattern or both?
Provantech should be 80% graphite and 20% fiberglass (same as the PB and PB Pro, it did feel a tad flexier, but it's defintely NO 50-50 graphite/fiberglass or the likes, at least from my recollection of my hitting session back then, but I am not 100% sure, since I don't own a Provantech anymore)
Consider the same 80 graphite/ 20 fiberglass composition Estusa frames:
PB Pro -- 65 RA
PB -- 62 RA
The graphite composition ratio alone may not determine the overall flex/stiffness feel entirely. PB feel WAY flexier than PB Pro, for example, despite the same composition ratio.
And Yep, I DON'T like 18X20 pattern. It feels entirely different from the rest of the Estusas.
Puma Super and Winner are MUCH flexier and heavier than the Estusa bunches (Estusas, like I said, were "modernized" in terms of weight, flex and swingweight etc, at least for those that I got in the early-late 2000s)
IMO, the only Estusa that you may find *a bit* comparable to Winner and Super would be the PB Pro, due to its heaviest weight (12.4 oz strung) among the entire Estusa range plus the 16X19 pattern.
