from what i've heard from users of the accugroove cabs, they're an excellent choice for anything. but those two eden cabs don't have much of a difference in low end response so you're not gaining any low end by using the 115. just has a tone you dig.
but the cheap way, and what seems to be working for you, is just what you're doing. you're getting compliments...nothing more you can ask for. use the 410 on gigs and the 115 at practices. or maybe use the 115 on a gig by itself now and then. if it works better in practice, no reason it wouldn't work onstage unless you're big volume freaks. or just buy an accugroove. hey, it's only money.
