My buddy gave them a whirl in his FT/R rig. He wasn't in love with them and ultimately went back to the 185's. I'll drop him a line for his initial load.
I have not but bought some to test. We use the 200 Hybrid. From discussions with others we compete with, many people who did try them went back to the 200 Hybrids. Every gun is different so I'll at least try them.
