well.. since i already had the edge is the reason i am using it.. otherwise id be using a TST/Smarty stack. The only real downside to the edge/smarty stack is that you can't utilize the sweet timing of smarty. since you can't (shouldnt) stack two timing boxes. So i'll either send my edge in to get the Drag upgrade or sometime down the line buy a TST.

 

Alright, thanks... I already have a COMP but am wanting to upgrade to the TST
