I read through 123 pages of information about the ZF version and toward the end there was a brief comparison between ZF and GF V2. I started this thread so we could get some clarity. After reflecting a while...maybe I''ll just get the GF V2. Lol It seems to be the better choice overall. It seems to be the better choice overall.
