Cheap plug alert: (yea, I know, bad pun on using "plug" when speaking of a pro shop...)
Another North Side shop if anyone's interested, Chicago Bowler's Shop located inside of Brunswick Zone Niles at Milwaukee and Waukegan. Rich Blake owns the shop, he does great work, a very friendly and knowledgable guy, knows the game inside and out. I drill part time there as well and I'd definitely go there even if I didn't work there, great shop.
Gotta give Will some props as well, Will Clark out at River Rand knows his stuff, also very friendly, also very knowledgable, definitely well-versed in Track, Lane #1, and MoRich, among others.
