I have spooled my Amsteel both ways and havn't had a problem either way yet, but was kind of wondering what others have done. I too have 125' of 5/16" line and to not spool it nice and clean you have to watch to make sure you don't get too large in one spot and start rubbing the inside of the bumper.

I'll keep you in mind when I buy synthetic line for the Jeep.
