I have the OS VZR and have had no problems. I run at Crystal Park and find my motor to run very well compared to the others. With a few gallons through mine, I am still on the same original rod. I purchased a new rod, but have not installed it yet. With a good setup and clean driving, you will have plenty of power with the OS.
I just got a MTX-4 and I like it so much I want to get a MRX-4R too. I run at Revelation but I want to make it down to Crystal Park soon... real soon!
