PSA and relic/jersey cards

What has been your experience with PSA as far as them grading jersey and relic cards? Are they tough on these cards?

graded by them and they put them in waxs pack holders.
I have about (200) Frank Thomas relic/jersey cards and refuse to get them graded because of how stupid
the cards looks in the giant sized holders also the holders allow some cards to move in them and damage
the cards. One of the relic/jersey cards that I sent in for grading has been damaged over the years
just by handling the card. Also I have received cards from Ebay sellers were the card was damaged because
the card moved freely in the holder and have had to send them back.
