You should check with your PSO and see if can get it replaced through his dist or Storm. I have had very good results with Storm replacing equipment when the warranty was voided for what ever reason. Worst case call Storm directly, no harm in that.

^^ the above comments.

With just a bridge crack, should just be able to plug and move on.  Often bridges crack because of too much glue used in gluing the inserts in or because the holes weren't angled away from each other enough and met at the bottom.  Cracked bridge is a minimal issue and easily fixed.  I don't think a cracked bridge should be a warranty issue in the first place, vast VAST majority of the time it's a workmanship issue and not a manufacturing issue. 

I agree. Just go to your pro shop

Best bet is to get your PSO to plug and fix it.  If warranty is already voided you arent out anything.  You can get in a catch 22 situation if the drilling is proper though.  Storm won't replace a ball if the crack is not impacting your release.  They will replace it if the crack progresses but if you opt to fix it as a preventitive you void the warranty should anything else go wrong.  I have that situation right Noe on a Phase II.  I will probably have my ball driller fix it at some point before I need it in a tourney.
