Juro,
I bought a Redington AS 13/14 in April. Great reel with a tremendous capacity. I bought it because I have been using a 10/11/12 Windcutter cut 26 feet from the end to which I add the Windcutter 10/11/12 upgrade. Then, I add tips of 15 feet to the front of this creating a line with 74 feet of belly & front taper. This is a lot of line and a lot of very think belly to boot. I needed something with a tremendous capacity, just like you do to have 200 yards or so of 30 lb with the heavy line weight XLT's). I was using an STH reel rated for 225 yards of 30 pound with a DT12, and it only allowed me to get 70 yards of 30 pound backing on it with the above line combo.
It holds the above line and 275 yards of 30 pound dacron. The only problem is that it is no longer being made. There might be some still around though and it might be worth looking for one. I paid $130.00 for the one I got, shipping included. They listed for $200.00. Otherwise I'm afraid you will be looking at the high end and rather expensive reels like the Bauer or Abels, etc. that can hold WF14 weight lines and over 300 yards of backing. Sure wish Orvis left the Redington AS 13/14 in production.
