My first thought was to raise the flop. As played fold turn. Against this guy I'd start limping the button and seeing how he reacts to it. If he keeps raising your limps, then I'd limp my entire range, and of course mix in some LRR's. Otherwise just call and see a lot of flops in position. You could get into crazy preflop wars with this guy, but I think it's more +ev to play smaller pots in position with him, not to mention much less variance. How does this guy play postflop? Does he slow down past the flop?
