If I upgrade to a Beseler 22" lens in my projector, which field fresnel should I use: the LL Pro 650mm or the 3Dlens 550mm?

22" ~= 559mm

I'm thinking the LL Pro fresnel would be best, but I just wanted to double check. Thanks!

Yes, you'll want the 650mm Pro fresnels.

Thanks, sorry. I forgot about being about to search LL with google. I used the internal search, and it returned an error because "22" is only two characters.
