I tried my friends K90 for about a week and absolutely loved it. As such, I decided to buy one for myself. However, being in Australia, the string variety I had to choose from was very average. I ended up going with PSGD 17G @ 58lbs - a setup I was familiar with on my K-Blade 98. Apparently, that was a bad decision... I'm lacking power. I'm not saying that I'm hitting floaters, but the ball just doesn't fly as fast as I'm used to. So... time for a restring. My friend and I are both avid fans of Weiss CANNON's Silverstring. That's what he had on his K90 @ 52 lbs. However, I thought I might as well try a poly/multi hybrid. I've decided on SS for the mains, probably at 52 lbs (I string this @ 56 lbs on my K-Blade 98). However, I needed a bit of help deciding which multi to use, as my only experience with multi's was limited to a badly strung flexpoint racquet with NXT. The problem is that strings cost significantly more in Australia (my local pro-shop sells X-One Biphase for $80AUD, that's the string standalone), so I would need to buy a big batch from TW (to cut down the shipping overhead per string). This means that I won't be able to demo the strings myself. I'm considering the following multi's for the crosses: - X-One Biphase 17G - X-One Biphase 18G - Weiss CANNON Explosiv - Babolat XCel Power 17 - ISOSPEED Pro Classic 17 Basically if you could provide details regarding a suggested multi, a recommended tension, degrees of power/control I should expect as well as tension maintenance, I would be very grateful.
