I don't recommend the Fire Road. I have one and it is one of those balls that will fit a specific need, but shouldn't be purchased if you want it to do everything. With only one other ball that you own I would recommend something versatile that can fill a few needs. The Victory Road would be better for that. The IQ Tour would be the best Storm ball I think.
What is sore when you bowl? A lot of it could be posture or specs on the ball. If you are bending too much or not enough or if you have bad pitches in the finger holes, it can cause a lot of soreness.
