Perhaps it's like one of short pimple rubbers that can be glued onto your blade in two orientations? Although you would not be able to see the pimples, the orientation probably still has an impact.
I am a little ticked, quite like the art, and the 52 degree one should have a different one, can be seen on the jp site, also the eu site literally explains nothing about the rubber so in one sentence "Its our hybrid sticky rubber!".
The V versions from what I can gather are modern tensors while the H version will be an hybrid.
The V 47.5° and 52.5° are now available in most countries in Europe so I look forward to the tests.
They have been available for a few weeks in Asia and there's a review on Youtube if you can understand Japanese (sorry I can't post the link)
H might be the tackiest one, Z is the expensive "pro" version. I'm not sure which ones are totally different topsheets, I have seen images of V and H on this (crazy) youtube channel...
I think you guys are mixing the rasanter and Jekyll & Hyde threads ..
the J&H versions are V,X,H and Z
as AndySmith pointed out the Z version is the premium version.
The J&H concept is two opposing characteristics in 1 rubber but even after reading the description for the V version it's still a little vague. According to the description it combines conflicting performances "speed and spin" or "speed and control" and at different gears.
The X version will be focusing on the catapult effect.
You can read all the description on xiom.store by translating from Korean to your language
The translation seems to hint at a low trajectory until you add sharp bushing contact, which reminds me a bit of Tibhar Hybrid K3. I'm looking forward to giving this a go.
Can't seem to find a european store for the others though. Was hoping to try Z...
