Well, have used my 240 SX enuf to post a commentary. The spool without arbor fit an entire 300 yds. of 20# Fireline Braid! Overkill in fresh water, but possibly useful from salty shoreline. Yes, the wide narrow spool is great for casting distance, but does not adequately manage loose loop casting knots. Usually have a few to deal with, but coupla days ago throwing 1/4 oz. jigs in the ocean had a bad session with way more casting knots to deal with. Also, like online reviews stated, the spool retainer/drag adjustment nut would grab the line after a cast and loop the retrieve onto it making a big mess. Guess I'll have to grind off some plastic, & it won't be pretty.
Might be better with mono(untested), but I wouldn't recommend the version I have for braid.
