I've always wondered about this. I reckon that, yes, if you wind the line onto the reel the "wrong" way, it will be twisted <u>onthe spool of the reel</u>. However, when you cast and it comes off the spool, those twists will undo themslves at the same rate as they went on, meaning the line youhave out (i.e, the line you are actually fishing with) will not be twisted. Have I explained that badly?
'Ive tried it both ways - allowing for the way the bail arm rotates and just putting the line spool on a pencil and letting it spin - and I find the "wrong" way doesn't cause me problems. The "right" way does... The only time I suffer from line twist is if I have used the clutch a lot. The lack of bog fish I hook means that doesn't happen often...
