from the session i had so far and speking just for non-ffb sessionist
sunfire, gia primo..then ola
for the reverse head scissor i ould even put jenni czech in my top three to top 5. she is somehow very effective and powerfull with that hold.maybe ist the way her thighs are shaped and she does put your head the furthest up to her butt until she starts ssqueezing. but for a non-fbb, non wrestlergirl , model girls she has scary scissors( her figure four sucks, though).
from the girls already mentioned, i would love to be scissored by these:
Yasmin, Tyler Dare, Jen Thomas, an old girlfriend and beauty pageant winner, lia labowe, Cindy Huntress,
kassidy from london , xana told me, has very strong scissors as well.
