Go ahead and shoot me. I know practice, practice, practice...but in my case I dont have a lot of time to practice. I've been out in the GOM many a time...but i've never really had a reason to tie knots above 60#. I am on a 10 day trip this year on the Excel late Sept-Oct. I plan on crimping all my knots 80# and above. I'm looking at the Sato crimping set. They have a pro kit and starter kit. What do you guys/gals think of the Sato system?
