Hello. Soon I'll be buying the complete Ogre series (Solid, Pearl, and SS). I haven't heard anything bad about the durability of the coverstocks, but the cheap price of the balls has me slightly worried. Is there anything I need to know before buying them? Also what kind of cleaner do you guys use on these balls? One last question: What do you think about the combination of balls? Will they make a good arsenal? Sorry for my questions. I actually have been bowling for 14 years, a hook for 7, but I've never had more than one ball in my bag at a time, so this is all new to me. Thanks.
