@ANIMA I would agree that the Hydroshort in Helium is arguably the best Hydroshort you can get on the market right now in terms of durability, long lasting torsional flex, and the most consistent finely tuned shape with low foiled rails compared to Tomo tech & XTR. I would agree FW in Helium is best suited for mostly clean, smaller SoCal surf and the way the board bends back and forth through turns makes it easy to generate speed on top of the lift built into the design already. Timmy does push the stock Helium/LFT Hydroshorts and LFT Hydronauts in heavy surf in Hawaii and Mex. Johnny Norris is a great surfer although he never made it on to the CT, I believe he put some years in on the QS but never qualified for the tour, he rips on the Helium Hydroshort don't get me wrong. I agree with the key testimonials from the pros on assessments that the Helium Hydroshort is super fast and very durable. Although I'm not sure having seen a lot of clips of both of them riding the Helium Hydroshort & Hydronaut in Hawaii, Mex, SoCal and the wavepool that they are doing their best surfing aside from going fast, as all Tomos should.
I have ridden the Helium Hydroshort and LFT Hydronauts between Hawaii, Socal and Mexican points. The Helium Hydoshort and LFT Hydronaut feel so good as designs under foot, until I ride them in certain conditions in Hawaii where there is more power to the wave, surface warble, offshore wind, side shore texture or any kind of bump on the wave. They have skipped out, gotten held up in the wind, felt too corky to keep a rail engaged at high speed or flexed too much in a direction I didn't intend making it harder to trust on rail. I think the culprit is that EPS is more sensitive when responding to texture, power or imperfections on a wave. Stiffer fins definitely help mitigate/neutralize the increased sensitivity of EPS when you want them to settle down. Notice that Timmy almost always used the AM Techflex in his Helium Hydroshort, very stiff speed controlling fin.
My theory is that surfers like Timmy Reyes, Johnny Norris, Kelly Slater, Gavin Gillette, Stu Kennedy, Sebastian Williams etc who rip on FW Tomos are able to better adjust to the sensitivity of EPS given their ability and push them further than most surfers can, as evident in all the clips. However I would love to see a board test where all of these pros get a chance to test drive a Hydroshort, Hydronaut or any Tomo made in a high quality PU foam with the best manufacturing practices. I feel like PU would have better damping to handle the high speed a Tomo design can generate and increase the ease of putting that high speed on rail with more control, especially in locations like Hawaii or anywhere with extra juice.
