I have a CAP'd Pro as opposed to the MP and am currently trying out Poly/Multi hybrids to find a setup I want to carry forward.
It came with free stringing when I purchased it, although they couldn't CAP it at the time, where I tried:
- Volkl Cyclone (Black) 1.25mm @ 50lbs / Wilson Sensation @ 55lbs
After CAP'ing I've tried:
- Diadem Solstice Power 1.15mm @ 50lbs / Volkl Power Fiber II 1.30mm @ 55lbs
- Solinco Hyper G 1.05mm @ 50lbs / Volkl Power Fiber II 1.30mm @ 55lbs
Currently waiting for my coach to get back from Christmas/New Year break to restring with:
- Volkl V-Square 1.20mm @ 50lbs / Volkl Power Fiber II 1.30mm @ 55lbs
Out of the 3 setups I've tried, I think:
- Solinco Hyper-G felt the best when fresh (really nice ball pocketing), although it seemed to go dead fairly quickly.
- Diadem Solstice Power felt stiffer, but wasn't necessarily uncomfortable.
- Volkl Cyclone felt the harshest of the bunch, but I put that down to the Wilson Sensation (I know it's supposed to be a soft string, but i've tried Cyclone before with X-1 Biphase and Volkl Power Fiber II crosses and neither felt as harsh).
CAP'ing the Radical definitely helped with stability, as I was finding that pre-CAP'ing it definitely seemed to wobble if I was slightly off centre on contact. After CAP'ing it felt super solid on contact, but was an absolute pig to swing, I persevered however and now everything else feels flimsy in comparison
