Just wanted to post an anecdotal testimonial to this thread, with another thanks to
@g4driver.
So the same 3.5 male I converted from full-bed Addixion to RPX 1.30 / Cream 1.28 (in a crispy G360 Radical MP no less), sent me this shot a couple weeks ago, after finally breaking an RPX main at the
70-hour mark -- yes, you read that right -- SEVENTY:
He said playability remained excellent the entire time, snapback was pretty much as good as off the stringer, and -- most importantly -- his arm feels great.
For those who see that hour count and are freaking out, a gentle reminder: we're dealing with a partial-poly that is
~50% rubber and a multiester that is
>50% non-poly, combining to make a string bed that doesn't suffer from full plasticization.
Hope that helps someone who may be wondering what kind of longevity can you get from a setup such as this.
