The Stiga Helix Hybrid Hard is a tremendous rubber, and I would put it right on par with the Butterfly Dignics 09C, which seems to be the standard everyone uses when comparing hybrids. It offers excellent control, tremendous spin and surprisingly easy power. It also has a fairly high throw angle, though not quite as high as the Rakza Z.
I've tried a lot of hybrids over the years, including the Dignics 09C, Rakza Z, Xiom Jekyll & Hyde C series and Donic C2. They all have their subtle differences, but the Helix Hybrid Hard might be my favorite of the bunch. For me, it offers the best combination of spin, accessible power and control.
My only caveat is the weight. This is a fairly heavy rubber. I initially paired the Hard on my forehand with the Medium on my backhand, but the overall setup became too heavy, so I ended up removing the backhand rubber. That's something to keep in mind if you're particular about racket weight.
Otherwise, it's an outstanding hybrid and one I'd highly recommend.
