There isn't a thing wrong with the 8 bolt H1's. The 12 bolts are just rated for a higher load etc. With all the extra armor etc the military was using they chose to make abetter rated rim. For our rigs, which are sometimes lighter than when they left the factory (depending of course) the 8 bolts are fine.
I chose 8 bolts because I know they would be plenty good, and with the 12's being rated better, the price is usually/always higher. 12 bolts do have the advantage of having 4 more bolts to hold the wheel together, but I doubt you'de ever know the difference running the 8's.
Folks have been running the 8 bolts for years with hardly any issues.
