Mate,
Just to add one thing to the wise words already said... you'll never get line twist on an Alvey if the closest piece of terminal tackle to the rod is a swivel OF THE RIGHT SIZE. A lot of people use swivels that are larger than they need, therefore the swivel won't turn and you might as well not use one. I almost gave up on Alveys before I was taught this, now I use the lightest swivel possible and have never had a twist again.
Cheers,
Josh
