I must be weird because I hate ABU. I find Shimano way better, set-up & perfromance-wise!
That's kind of why I did the upgrades to the 6500s.
I started out with a Calcutta but burned it out after 6 or 7 years and now use a Corvalus for most of my fishing.
I really prefer the free spool lever setup vs the button on the Abu and was kind of disappointed in the performance.
The original plan was to use the fully upgraded Abu for a backup reel but it is now going to be my steelhead reel since it performs so well.
The lesser upgraded Abu is now going to be my backup reel.
Just a note that A&N in Langley had some great deals on rod & reel combos.
They had a 6500 and Convergence rod for $144.
They also had deals on Shimano combos - I think the Corvalus combo was around $150 and they had another Shimano combo for $160.
I forget what rod they had in the combo - it was not the Convergence.
