Very splashy Aggro recreational limps ep covering table

Aggressive rec raises to $30 CO and is 200bb deep (I saw this same player raise J7s in ep to $15 as open raise, call a $90 3b, then shove a J8x flop for $350 over a cbet from an older guy; also saw him raise BB to $35 w two limps to $35 w A3s)

Hero on button w AJo and 200bb deep

I fold

I’m wondering if flatting is an option given the limper. He is a very aggressive unpredictable player and def getting outta line.

I’m also wondering if this is a 3b being 200bb deep. I think I would typically use this as a 3b in this scenario for 100bb, but as I’m getting deeper, I’m thinking hands that are suited and have more nut potential are going to be more valuable. Because he is calling so wide preflop, it seems like a hand such as A5s wouldn’t play as well, and using a top heavy linear range would do well. Something like A9s+, AQo+, and then mixing some QJs, KJs, KTs as flats and 3bets. AJo seems like it could go either way between a reraise or a fold. While AJs is def good enough to just be 3b
