From June 2012: Why Deep? Well that was my first question. The answer is a simple one - the reel is a sort of large arbour, but it's not! confused, well don't be as the concept of this reel is simple yet clever. There are occasions when you want a load of backing and others when you simple will not get a fly line, yet alone backing, on a traditional large arbour reel. e.g. a distance line like the Snowbee XS Extreme Distance is a whopping 150 ft long, or a Royal Wulff Triangle Taper Nymph has a diameter such that it takes up a lot of room on a reel. These lines will not fit comfortably on a large arbour reel with a reasonable amount of backing. Enter the Deep. Now this reel (looked at in section) has a deep (hence the name) groove to accommodate extra backing or some of the running line of your fly line. Brilliant! I use a few lines where I've been unable to have more than a couple of metres of backing because the reel spool is not designed for these specialist lines. The Deep is a cast aluminium, machine finished, reel. It looks good, very good, and is available in white, grey and black. It's reasonably priced, has a great disc drag and simple spool change. For me, it's the answer to the ever-present problem of how to house a specialist line on a large arbour reel.
