I've used the 151's / 251's and now the 401's.
I love them all,It's hard to go back to a 5501 or 6501.The drag system is ten times the system on the ambas models.I put the 401 on my meat stick for the bouy ten fishery this past summer,I liked it so much I purchased a nother one for my kwikfish rod.The 5501's and the 6501's are for loaning to others while fishing on one of my boat's.As for any other reel,alway's back the drag off when not in use.
Good luck,
