The new 507 works on a different drag system much like a conventional fixed spool with the drag connected to spool system not the bell.
I looked at them when they first came out on the market I never bought one because in my opinion there very big and heavy for a modern light match rod.
I am pleased I never as there has been major problems with the way the reels operate and are put together.....
Similarly, I was tempted to try the 507mkII as an upgrade from my 506mkII, but when I had a feel of one in the tackle shop - I decided against because of the heaviness and clunky feel. I have persisted with the 506 but find it seems to be on the way out
Over the last 2 years it seems to have developed one small niggle after another!
- sticking bail-pin - preventing retrieve
- non-locking spool fixing lugs
- spare spools of slightly varying widths causing 'scuffing'
- erratic clutch engagement and action
- sticking anti-reverse switch
Alright - none of them are major 'stoppers' - apart from the latest trick with the bail-pin sticking open. This persists even though I have cleaned, lubricated and checked it, - it's back again after a dozen or so casts
I liked the initial ease of use of the Abu and feel of it when fishing - particularly the lack of 'bumping-off' fish when the bail engaged - not so keen on the lack of winding-power when hooking 'bonus' chub, barbel or trout when trotting for dace or roach
Thinking of trying a Daiwa 125M now their prices have come down to under £60 from a ton - What's the biggest difference I'd notice?
Shame that there's not much more choice in the market - all the (better?) old models have seemed to disappear!
