.5/1 to 1/2 (6-max) transition

[Yobz]

Hey guys, been here a while and I've been doing .5/1 for a while. I feel like I can 4-table it pretty well but I feel like I'm a little over-aggressive for such low limits. I think I can better use my aggression in a 6-max table and with the party reload my bankroll will actually have 450BB for 1/2. Do you think I should move up?
Quick stats:
Only have 5k hands at .5/1 and I know this is not nearly enough (yes I really do know) and have been pulling in 4BB/100 or so. VPIP of 18% PFR 9%, 3-4 agg for flop/turn and 2.5 for river.

Should I take the jump? Anyone have hands on me in the PT database and wanna make some (preferably mean, so that I can learn) comments?

Thanks!
