BB30 and Shimano road cranks: which adapter?

I'm getting a new CF road bike frame that includes the BB30 bottom bracket design. I'm going to use an existing Shimano Hollowtech II crank-set.

I would like the most trouble-free adapter that will allow me to use the Shimano crank. I just want to be able to enjoy the bike without creaks, re-fitments or any risk of damage to the frame.

I'm looking at the Wheels Manufacturing adapter: http://wheelsmfg.com/content/view/785/54

I'm also looking into this adapter that includes external bearings;

The KCNC BB30 Adapter from LightBikes.com (scroll down): http://www.sales.light-bikes.com/kcnc/defaut.asp

Any other suggestions? Is one going to be better than the other?

I think the kcnc is best. No press in problems.

My KCNC BB adapter failed at 2000 miles. My first BB failure ever, however, I'm not sure what caused the failure.

The Wheel Manu unit is fine. No trouble through several crankset changes.
