As I said in an earlier post, wheel statics and dynamics are so complex, it is hard not to miss something in a quick and dirty perusal.
Thats a good point about the drilling being compatible - not all hubs would allow it. I guess the other consideration would be the deflection of the flange itself which would be larger with radial and reduced with a cross lace. Not knowing the sectional area of my hub or the exact alloy properties I cant calculate how significant that would be but I would think the bracing angle is far more influential.

I earn a living using finite element analysis, Ive often thought that one day I'll answer some of these questions for myself but I never get around to doing it. Too much like work I guess.
