my vote is for smarty if all your interested in is smoke then the only way edge will do it is with the hot unlock, but the edges do tend to run hot egts though. but i would agree i kno alot of dudes that had the edge and got rid of um for the smarty because of issues they were having with them. the cummins do tend to run nicer with the Smarty IMO
