Build It !
U really sound like the kind of guy that will look at everything , and KNOW u can build something more appropriate for your round of DG !
I'm in love with the Chally pack , but I'm trying to step up to playing tourneys and fit in with the chillas ! Really hope Santa got my note and has ordered me a RED and WHITE CHALLY !
You should search the homemade bag forum , theres a couple of good ideas for modifying a Cabellas fishing pack into a decent beer/disc pack . More ideas for an internal frame so u can sit on top of it . Had to build my own and it works great , but now I want a smaller pack ! Really should take photos but I'm packing for a move so computer is packed !
Good luck , search the forums !
