I have no idea how far your casts typically go but I would think that would be enough. I don't really measure mine. When I put braid on a setup, I put on a practice plug and cast it toward the neighbors driveway. I go to the plug and walk off 10 more yards. I go back to the house and cut off the line, tie on the braid and put on what it takes to nicely fill the spool. This has worked for me since I started using braid close to 20 years ago.
