i have used the shimano reels first referred to, and the spinning roller helps reduce line twist so i dont know what they are on about,as far as loading line onto the reels spool, ideally you want someone holding the line you want to load onto your reel, with a pencil through the middle, and making sure that it is facing the same way on which it is going to be loaded onto your reel.Also if using pre stretched or semi stretched (such as super shinobi) this will have a tendency to spin up on the reel roller than older more durable lines (such as bayer, maxima etc).
