I have discovered that I don't feel as comfortable with those little pistol grip thingys, either. I don't know why, but, straight grips work out better for me, on a Darne. Rabbit's wood removal cast system is the only one I've seen like that, and while I have no doubt it wooks, the image sticks a bit in my own craw.
I can't say I feel revulsion at the sight of those semi-pistol bumps, however. I just notice that my specs become ever more deeply etched into stone as time goes by. Might be an attitude thing. But, more likely an age related issue.
Best,
Ted
