Hello, hoping someone can help me with this. I don't get the OPST line recommendations.... Says I should be around 325-350. I have TFO Deer Creek 11' 7 weight switch. Currently casting 480 Airflo skagit scout on and really like it. So I bought a 450 commando groove. I based this on a guess...

Worn but still fishable. Frayed back loop from use with Lazer running line. $20 which includes shipping.
