No I don't have any personal experience with the Vinci. One of the guys in our group shoots one. Seems to really like it. Make sure you like the safety position. I'd throw both the SBE2 and vinci up and buy the one that fits the best.
SBE2 has been great for me, also left handed which really got my interest. As long as you keep the bolt and slides lightly coated in lube you will never have a problem.
If money talks; then I got a lot to say i'm on the grind trying to make a hundred thousand dollars a day! We play with big cash and we blowin money fast. I need a G for every light bulb on the Vegas strip!!!
