Greg, FWIW, when I was collecting this set '04-'09 I cracked about 3 dozen SGC slabbed cards and they all crossed over to PSA, a small portion at either half a grade higher or lower, since PSA didn't have half grades at the time.
The only set I haven't been able to cross over at the same level is T200. SGC seems to grade those 2-3 grades higher than PSA, and I eventually gave up trying since it always led to brutal results.
