Hi Morgan.
You should adapt well using your experience as a river angler, although some of the flies and lures you will use will look a bit, shall we say big and awkward.
Arm yourself with a few cats whiskers and taddies, knock up a few bobbies and blobs, do not forget the shipmans, cdc's and F Flies. OH and some buzzers, and when things get really tough revert back to your river box and pick the trout off as you would in your local river.
Most of all enjoy yourself, and do not be shy to ask your fellow members for advise, and you will have a great time.
All the best let us know how you get on TK............
