Both are very good clutches and from a price stand point I think there within $25-30 apart.
One of the most important thing about clutching is support. With so many variables getting questions answered can get frustrating.
VFJ has great customer support and answers all his calls and is the only one that carries the Team Clutch for Can Ams.
CVTech - Several vendors, some suck some good. Below are a few vendors I dealt with.
3P Pit Performance - Great support and carries several brands.
\\\airdam very difficult to get support almost impossible to be reached. I gave up.
Direct from CVTech - minimal support, they will just give you basic setup.
I have CVTech/STM combo purchased directly from CVTech and STM.
So for me I was pretty much on my own to dig out the information I needed for my setup. Not hard to make changes, just time consuming trying different setups. If you want to save time then buy from a vendor like 3P.
CVTech has several primary springs to choose from, all depends on what engagement and finish rate you want. This is the most difficult part of CVTech, picking the right spring.
Weights are very simple round coin shaped design and can be easily drilled for lighter weight and you can use simple washers or even pennies to add weight.
VFJ clutch I don't have any experience with but from what I hear it's similar design as the QSC. I have a basic idea how to set it up, but don't want to speculate as I haven't. So I will leave that alone for someone else to chime in.
From what I gather around my group of guys that I ride with. The guys with big tires and like to mud lean towards QSC. Fast trail riders like the CVTech for it's quicker throttle response.
One last word of advice I can give. Don't just stay with the setup they send you. Try experimenting with a little tweaking of the clutch. You can have the fastest setup for the track but might not be the best for everyday riding. Try different setups and see what feels best to you unless your racing everyday.
