I got a set of frags awhile back to take for a test drive. The more I drive, the more I like. They are becoming my favorite VZ pattern.
I want to try a set of the palm swell G-10's next. I might like that drive too..... 
I've got them on my P-01 and they are great. They took a good bit of filing to bring down the sharp points but I've got them right where I want them now.
Got any pics?
Made a quick video. Sorry about the quality. It might be hard to tell but the tolerances are very good, they fit flush. I opted for the thumb release cut out, and I like it. I was a hoping a video would display the palm swell a little better. The top and bottom of the grip where it begins to flatten out can be a bit sharp, but the dye is throughout the material so filing does not effect the color or finish.
For whatever reason YouTube took the resolution down to 320p so if anyone would like me to send them the original video via text I'd be happy to. It does the material a bit more justice.
