i play with two bowling balls in my bowling league - track emb and a brunswick eliminator. these are old but hard hitting balls. i feel like the track ball is losing its hooking power and the eliminator is unpredictable but hits hard. i was ready to give up the track ball but at the end of the 2nd game it got me about 7 strikes in a row and i ended up with a 188. but the 3rd game i had at least 8 strikes in a row and ended up with a 255 game. as for the eliminator, i started my first game with five strikes in a row but it kind of lost its hooking power after that fifth frame and i ended up with a 192. my scores was  192, 188, and 255 that night in the bowling league. should i stay with these balls  or move on to more consistent balls?
