posting here is fine.. if you are looking for a certain company you can post under them also.. for a question like this you can post under miscellaneous for bowling(there are 2 miscellaneous, make sure you have the correct one when posting), beginners board or another company.. someone will answer your questions most of the time.. a replacement ball for your stinger would probably be a light/med to med ball..
900 global a link, creature, creature pearl, maniac, lunatic
amf a heist, villain, the code, night hawk pearl they also have some newer stuff out too
storm a t-road solid, t-road pearl, fast or a furious
roto grip a illusion, grand illusion, normad solid or pearl
the list goes on from columbia to brunswick to hammer etc. etc.. etc...
look for a lower costing ball to start.. you really don't need/have to go out and spend alot aof money right away to get a great ball.. work on your game(maybe talk to a coach or one of the better bowlers you respect and have them watch you)) and go from there getting into the more expensive higher end balls later.. hope this helps alittle and keep the questions coming.. someone will definetly answer you.. slashrr69
