Argyrotype Paper Problem

I have recently started using the argyrotype process
and have run into a problem. Using Crane 90# cover and
a puddle pusher , I am having very inconsistent
results.
I get an even coat, but sometimes I get a splotchy
effect that shows on the opposite side, and also in
the finished print. Is this a problem with the paper
or the amount of Tween that I am using (1-2 drops per 5ml)?
