MH reflector Question

[gixxer600]

I am putting together a standered 90 RR tank and i am going to do dual 250w Mh and i was wondering what you guys/gals would suggest would be the right reflector to go with. I was thinking the lumenbright mini but i have no experience with the lumenbright line. Is there another brand that i should consider or is the lumenbright the way to go? Thanks for all the help.
