Since I have only had these balls a few weeks, I've not bowled anything other than a THS. I have started with the Zero and transitioned to the Fusion, sometimes not quickly enough. Like last night when I went 237-185-247. These are also my first 15lb balls, so I'm getting used to the lower weight and slight timing difference. I do not have a lot of rotation and plenty of ball speed. All balls are drilled aggressively to account for these two factors.
Yes, a Storm or Roto preferred.
