I would highly recommend you check our Jaeger Archery. He makes replaceable grips for metal riser, mostly ILF bows. I know you can't use the grip on a wooden riser bow but you can see what a great grip should feel like.
These grips aren't cheap -- $59. However, many a $1,500 bow has been tossed aside (sold or gathering dust) because the grip didn't feel or work well.
You might also buy a grip designed for a metal riser from Trad Tech, Das, Morrison, 3Rivers, etc. What you'll notice about these grips is that they are "technical". They've been designed with accuracy in mind. They borrow a lot (all?) from target archery.
I just sent a TT grip that I love and a custom riser to a bowyer for a reworking -- trying to save that bow for me, which I already have more than $1,900 in (2 sets of limbs).
For me the flat palmed, medium grips that taper at the heel, especially to the bow arm side, are the most torque-resisting grips.
