i wouldn't count out the Groove so soon. They are definitly more than they're worth. Even with the core type it carries like a truck. I have found the Punisher to be a little touchy on tougher conditions. Thats something you won't have to worry about with the PK18 cover on the Groove: more so when your track wears a little bit. Drill it with a semi-strong drilling and watch the pins fly. Keep in mind this is only what I have experienced I DON'T KNOW how you throw your ball!!! Hope this helps.
