"Every time we've been at it, Strider either perish due to Random casualty"
The trick is TAKE CORRUPTION.
When you hit 8 corruption, then start taking random casualies.
You cannot roll a 1 if you do not roll.
", or the lost Action Die really hurt the FP."
Nailing (and rezzing) Gandalf early is better than getting Galadriel in a sprint.
Strider uses the spare dice to hide and Rings to move.
Galadriel isn't that useful in a true sprint.
Killing Gandalf does not take a die to separate.
Against 0 eyes in the box consistently, strider is better as Aragorn, in my opinion.
He does not get to use his ability to hide the FSP, because the never find you!
I think Strider Sprint is best against someone consistently placing 1 eye.
But that is a very hard thing to quantify.
