Overloading
I've overloaded as much as three line sizes when conditions dictate (wind). The only true way to find out what wieght line to use is to try them out. You may not have to got to a 10wt., you may be better off with a 9wt line with a heavier foward section. My suggestion to you is to go to one of your local dealers and try out a couple. If they are a good shop they should have demos on hand. If not any of the Orvis stores around are great for trying different lines.
