I'm just a hack (183 composite average), so consider the source!
I have trouble trusting my ball, so I thought a slightly stronger version of the EPP would be a good choice, since I love the EPP. I haven't thrown the DC enough (10 games -- one 4-game set and one 6-game set) to make a fair comparison. I shot two 200+s the first four games. I'm rarely successful with a new ball, with the EPP being the exception (shot 298 the first day). In addition, I'm having some thumbhole issues (too large) with the Depth Charge, so my release hasn't been as consistent. I'm needing too much tape the first few games for a comfortable fit. I'm going to get it reslugged for the winter when my thumb is smaller. It's not my driller's fault. When I told him to open up the thumb more, he was reluctant, and told me that it was a very warm day and my thumb was unusually swollen.
The games that my thumb was sufficiently swollen to get a clean release, the DC had a stronger move to the pocket, but not necessarily much earlier than the EPP. Both balls are drilled about the same (EPP about 4X4 and DC 4X3 7/8), which leaves the pin next to the ring with the CG (the EPP 2-inch and the DC 3-inch pin) stacked for the EPP and very slightly kicked out for the DC. The DC has a larger weight hole. I stood at 25, drifted to 20, and threw it out to 10 (so it would actually be about 13 to 10). The lanes didn't have fresh oil (but they weren't bone dry), and there was some carrydown.
I finished the last three games of the 6-game set with a 600+ series. Thus far, I prefer the EPP for its predictability, but that may change once I get used to the DC.
