Blackhawk grips

I have a couple of Blackhawks in .45. I haven't ever liked the factory grips. When I wrap my hand around the grip my middle finger doesn't match up with the lines of the grip, and it's uncomfortable. I want some rubber grips that are a little trimmer and no finger grooves.
The problem is that there are at least 4 choices, probably more and I don't want to spend the money trying them all out looking for the best match.
I have about average size hands for a man and I'm looking for suggestions. I do NOT want a huge grip that bridges the gap between the frame and trigger guard. If it's any help, I find the Bisley grips *very* comfortable.

I know there is a company that makes wooden fingergroove grips in a semi Bisley style but cannot 'member who right now.
Try asking this question over on www.RugerForum.com for a better round of answers. I have two Rugers that wear Pachmayers at times. One "Grippers" and the other "Presentation".
