You can dent any rim, you can taco any wheel. There is no bomb proofing. A wheel built by yourself, I hate to say this is not going to be bombproof unless you are a born natural or have done it many many times. A wheel is bombproof because of the accuracy to which the spokes are tensioned and to a minor degree, whether it is eyeleted or not. A cxp33 is a very good rim and the spoke won't pull out the rim at the eyelet (because there are none) which I have seen happen on an MA3. The quality of a wheel is in the build, an open pro/phil made by a machine is going to suck no matter what, built that combination built by a seasoned pro will be much better.
