Hi Nicole
Erh, best skintones you say ? Hmm :-) I did some Agfa RSX 50 some years ago and to me that was the best film for X'ing. As mentioned the Fuji and Kodak have some nasty green and yellow colorcast. I didn't experience that with the Agfa.
When overexposed it does make an in my oppinion nice effect on the skintones. That is if you want the almost white. For sure it is fun.
BTW I never filtered any of my shoots.
