I have used vertigate with syncros
![Shocked](http://cal-look.no/lounge/Smileys/default/shocked.gif)
Worked fine and didn't chew them up, lasted all season without any problems, then just freshened them up during winter, now I have pro rings/slick shift and go a season at least without needing anything, the thing for me is adjust the stops correctly on shifter, it takes time and most problems I see are from over shifting and banging past were it needs to be. I do always use clutch to shift though
