Well we all know the Pro is more than likely over graded or altered as most are so why waist the money. His preference to do the GAI's only is just that, preference. I have bought 1 GAI card ever and it was my WOJO T205. I was lucky that it did cross and I lost a full grade from an 8 to a 7. I was more comfortable with SGC's 7 than a possible GAI 8 flip on the card if I had to sell. Sadly enough due to a family issue with my youngest I had to sell. Big regret but some day he will return to my registry. It has a sense of validity when SGC and PSA grade a card numerically, as compared to GAI, PRO, CSA, and so forth.
