I know there is a BB30 expert here somewhere (is Campag4Life?, I can't remember but anyway)

I took my SuperSix in yesterday to have my Sram crank installed and the shop used these Wheels Manufacturing adapters:
Wheels Manufacturing BB30 Shims for SRAM | Amazon.com: Outdoor Recreation

I'm having the same problem as the review on there with the guy that also has a SuperSix. To get the crank to spin freely means having to almost not torque down the crank arm and that leaves play in the crank/bearings. But to torque the crank arm down to spec binds up the bearings to the point where the crank will barely spin at all. So basically the mechanic tried his best to find a happy medium, put on some blue loctite and told me to keep an eye on it. I said ok because I want to ride my bike but the more I think about it the more I feel like this can't be the correct long term solution. Anyone have any experience with these adapters or have any idea what might be going on?
