Several dozen wheel sets under my belt - The big stinky secret is that there is a wide range of tension that works for any wheel. I've found that about 70% to 100% of max rim allowable tension gives a wheel that rides well.

Also, it is more important that the tension be even on either side rather than set at any certian tension. If you're within 5% for spokes on a side, you're golden. 10% ain't gonna kill you either. So having a calibrated tesnion meter is far less imprtant than having one that reads consistently. My cheapo chineee thing works well, and I don't care if it is 10% off, as I don't wind spokes up to max anyway.

This ain't rocket surgery, only playing with spokes and hula hoops.
