Actually I've been there about several dozen times, trying different combination, and it all has led me to this.

According to that site a 20/24 combo for me would be ideal considering my weight and amount of riding I do, but many

different forums, wheelbuilders, including the infamouse Ergott all have different opinions.

Btw Ergott recommends a 24/28 CX ray build. I told him I would rather go round double butted instead of bladed, but he

hasent got back to me on this yet. Are the CX ray stronger than a double butted spoke like DT comps or Sapim races or

leaders?

"a bit fatiguing" after long rides?

Thanks.
I bought wheels from pro wheelbuilder this time last year and am very happy with them (Pacenti SL23; sapim cx ray's 28/32; brass nipples; dt swiss 350's, around 1635 gms). I'm 240 lb's. I think Ergott's 24/28 CX ray suggestion is good advice. The 20/24 combo will buy you a few grams and save a buck or two but will offer no other advantage and you would have a reduced margin of error in the wheel strength. No matter what your weight is you never know what you are going to encounter out on the road as there are always times when the wheels will need to punch above their weight. At around 4.4 gm's apiece (CX Rays) you'll need to decide if that extra 1.25 oz's is worth it. The difference in the fatiguing factor would be negligable when comparing 20/24 double butted to 24/28 CX rays. Take 2 or 3 psi's off your tires if you think that is an issue (which is isn't).
