I am currently rolling a Resurgence, and I absolutely love it. The only problem I am having is the reaction with carry-down and the heads burning out.
The first game of my sets have had good reactions, and everything is pretty consistent. The second game has been iffy if I am bowling with people who don't throw similar lines to myself, and in those cases, I completely lose reaction in the third game.
Now this is where I seek opinions... I don't have a ball I feel comfortable switching to in those situations because all of my equipment is old, and it is just as iffy. So what I am looking at getting is either the Rival, Momentum, or High Flush. I know all of those balls could be strong to start a set with as well as end with.
So any input any of you have would be much appreciated.
