[O.B.Left]

I'm partial to interlocking for now.
For me I prefer to have a bit of the left forefinger between the metacarpal joint and the proximal interphalangeal joint on the shaft of the club. I'm not aware if I point the rest of it or not, but my left forefinger is definitely involved in the grip.

I couldnt agree more and was about to say exactly that.

There's more than a few majors won with that grip Dlam.
