Traditional fly reels have to be filled up with lots of backing, far more than is necessary. Not only that, the small diameter of traditional reel cause horrid kinks in fly lines. Not only that the small diameter means that the line retrieve rate is slow.
Large arbour reels are marvellous and worth every penny. I own two Dragonfly Large Arbours which are not expensive and they are British.
I agree with Ron,but would also look at the Orvis Rocky mountain LA & the greys GRX both are british made by BFR down in Falmouth.Most have disc drag now so same as my last post spend what you can afford.The saying goes you get what you pay for.
