My mod would have to be my Kicked ELA from Super-T I got coming in a few weeks hopefully! As far as what's on top and had to pick just one, Terminator. Best of both worlds, a tank I can drip on. That is unless the Strata ever comes out from Super-T to make my ELA a hybrid.
EDIT: If we are going juice as well I'd have to say my "Misty Mint" DIY Homebrew. It's a new one, but an instant classic.
