Viscous fan question???

So last week at the Spring Fling I bought a fan for a good price P/N 2863216. I got home and cleaned it up mounted a new Hayden 2765 clutch fan on it. I installed my new aluminum radiator and the new fan and noticed that one of the blades was bent and was hitting the radiator. I took it off and bent it back. I just did not feel right about using it, due to fact that it is more than likely out of balance.

So I got to looking for a new fan. I see that Mancini racing has a 6 blade viscous fan set and it looks to be the same one the Bouchillon has, but Bouchillon sell the fan by itself. However, Bouchillon has a disclaimer stating that this fan is to be used with Bouchillon thermal clutch only. I do not know if that is a sales gimmick or not. To the point, I was wondering if anyone has purchased this fan and used the Hayden 2765 clutch fan with it. The fan is an 18 fan 1/2 inch smaller than the 2862316.
