I was asked to make public what is in my private PM's.

To minimize dish remove as many washers/spacers as possible from the driveside. Space it so your chain is right next to the droput. On the NON drive side add spacers to achieve your desired width. If your starting with a 126mm hub and space out to 130 your decreasing your dish by 4-5mm. Using a 135mm hub you'll decrease your dish by a minimum of 9mm. Both of these scenarios are with a standard rim. With an 'offset rim' dish will be reduced further. With the proper selction of componets 'negative' dish is possible.

If you have a choice of lacing the NON drive side 4X 3X or radial the radial lacing will have a higher tension because the spokes are shorter. Think of a drooping wire on a telephone pole. The shorter you make that telephone wire the more tension it has. There, of cours, is a trade off to this. If your a believer in the 'S' theory you wont break the heads because the spokes not losong tension the regaining thus beating up the spke head. But, you will risk ripping the spokes out of the hub because of the increase intension.
Radial lacing as solution for 3X/4X spokes breaking on the NON drive side is a poor solution to the problem.
If proper equiptment is selected and a wheel is properly built pedaling forces shouldnt slacken the NON-drive side.
