SGC to PSA Experiences and Advice please

Again I dip into the vast wealth of knowledge everyone here has. I have a vintage football 57 Starr graded SGC 88 (8). I wanted to know about sending to PSA for a crossover. I do not want to crack it out and throw the dice. What experiences has everyone had with sending cards in for the crossover. Thanks as always.
