Not a fan of the small boots on 934 CV's. Sure the bolts are exposed but any car I've prepped with them also slings CV grease everywhere. The CV grease works its way through the bolt holes or in between the flange and CV body. Yeah yeah, I know it's not a problem for 'you' and your boots don't sling grease, just saying what I've seen on numerous cars I've prepped.
@tjZ06 Potter was slinging so much CV grease from the small flange boots we swapped them out for the Bates over-boot. Problem solved.
I have a double boot system on my car, small inner rubber boot and large leather outer boot. The small boot definitely keeps the grease in the CV better but I can't get even a half a season without the small boot tearing. DGAF, I keep running them.
As far as what CV grease to use- I speak from experience in my 10 years of prepping two Class 1 Unlimited cars that ran 250 to 1000 mile races. We used Swepco Moly 101 and BelRay. We didn't mix it by hand or buy it premixed like Foddrill sells. I packed the CV using a needle tip with Swepco then put a layer of BelRay using the caulking tube over that. Definitely NOT a 50/50 mix, probably closer to 75/25. I do the same thing on my personal car and every single car I prep. I've only ever had one client request that I use Elite grease but that's because he had a case of it in his trailer. I have no issues with Cat Desert Gold or Elite, or whatever it's called now if that' you preferred brand. But if Kartek and McKenzie's don't carry it, that means race teams aren't using it. Race teams use what they know works, not what they can get for half the price of BelRay.
That being said, I'm calling Foddrill tomorrow to order some.
