200nl: Lead turn or CRAI to extract?

[BlackAMEX]

Villian is 42/22/6.

Is CRAI or turn lead for 1/2 pot better here?

I think by CRAI we let him know we have Jx here, and if he has Jx, he's stacking off anyways no matter what line we take. By weak leading we may be able to rep a pp trying to get to showdown cheap rather than JJ, and hope that he pushes as with a wider range of weaker hands.
