I run the AA 8's and thoroughly love them. I've also heard a sealed L5 8 and was also impressed by the little guy. I'd personally go with the AA's over the kickers. You can get some used AA's or wait for the v.2's to come out (I cant wait). I've head great things on the TC's too though. Hard decision. For the money, I think i'd try the TC's over all.
