jmatt, I have a few 1/4 bent Rhodesian and Bully's and they're wonderful. They aren't quite as clenchable as my old straight stemmed Linkman's Supreme Rhodesian, nor as light.
I smoke em a lot. If the button is just right, as it is on some but not on others, I can clench them without concern, but if the button is 'off' either way, not as easy to clench that bend. I've had em drop out once or twice.
Now, another shape I do like is a half bent...they're slightly more able to clench for me, and WHY should I be so concerned about clenching? Well, touch typing requires both of my hands.
