Little Hero is the way to go if you want the best... his new versions have more subtle AR, very gen-like.
If you don't want to spend that much I would look for a nice modded one (EL, DSN) from another member, re-lumed, CP-fixed, maybe a better CG. Should be roughly half the price of a LH.
With see-through casebacks you will always have the movement issue... no rep movement is near perfect, still LH is the best one here as well.
