hi richard
okuma airframe is an ok reel, had a couple myself. pretty bomb proof, would buy another. if you look on ebay you will find a reel plus 3 spare spools for around 35 quid. If memory serves, it is only in one size, 7-9wt.
only negative is that the star drag adjuster, which is nice and easy to use, also has a gap down the side which can catch the line - bit silly design, but otherwise light and strong.
I have come to the view that unless you are going for serious fish or you like a bit of tradition, then a simple reel will do all you need. Most reel design is about seeing how cleverly the manufacturers can waste aircraft quality alloy. Things of beauty, but really, what difference will a fraction of an ounce make? At the tip of the rod maybe.
Personal view only, priority of spend - rod, flies, line, waders, shades, sandwiches, reel. Oh, and licence and 12 bore. For research into cormorants.
but what the heck - boys' toys, eh?
