Well I had some 1.20 cyberflash and I tried it with the same OGSM crosses. So far I do not have the same amount of control and surprisingly the spin is better with the 4 as well. I did not expect this to happen. The weirdest part is the comfort is better with the older 4g, and I know cyberflash is rated as one of the softer polys...interesting.
