Great title. Hope it all works out.

I think you got a fantastic game at a super fair price! Congratulations! All those minor issues are a great way to get comfortable working on your new game.
Awesome acquisition!

Titan has a database where people put there own rubber and ring combos on there for others to use. Some have photos. All put together in a nice package and you don't have to search sizes.

Just select the blue type under "kit type"or "submitted by" to view the kit.
If you see one you like just select the "view full kit" button on the top left of the one you expanded.
It will open up in a new screen and on the bottom it says sign in to customize and purchase.
I wrote this out because of the somewhat cryptic process titan uses to get to these.
