I jam J high flop anytime. I consider jamming K high flop if I think villain is agressive and attacks limps with junk. I generally don't like limp/calling.

I agree about limp calling, I find that a more narrow type of opponent is often the only thing that leads to common limp calling situations in hyper turbos, as I'm likely minraising a lot of hands against many opponents at these stacks.But say you have a guy that has let you limp a bit, but he 3bets fairly wide.  T9 or 98 is a hand you might then limp, it flops well, you can often see the flop for just a completed limp action from the sb and minraising would often result in your opponent jamming and 98 type hands aren't really favorable for the most part minraise/calling (and MR fold is not too great either vs a wide jammer).As far as postflop play goes, it really depends on your opponent, but when you're playing a 6bb pot with 11-13bb behind, you need to be able to really narrow your opponent's range down to a lot of strength to fold 2nd pair.
