I am going to be in the Vancouver area the first two weeks in April and am looking for some places to get a fly bit. I've been fly fishing for decades and want to help my brother get started catching some steelhead, salmon, trout, whatever I can while there. He's been fly fishing for a few months but unable to connect with anything other than very small fish. I have the knowledge and equipment but don't know where to go. Any advice/help would be greatly appreciated. Rivers, flies, techniques are ALL welcome.
I was out with him last summer (June) and accidently connected with a steelie

but broke off immediately. I had no idea how powerful these things are, I'll be more prepared this time around for how tough they are. We only had a very small amount of time to fish then but will be without our wives this go-round so we can fish til we drop this year.
I have some limitations on how much time I may be able to spend wading due to an uncooperative knee replacement (a long story) and will be bringing a tube for relief when the leg gives out on me

, and it will, so we will also be doing some tubing for trout, bass, or whatever, all suggestions welcomed here too. I am a prolific tyer and would like to whip up a bunch of flies for whatever we might encounter in the local lakes. I already have the standard assortment of damsels, midges, nymphs for caddis and mayflies, leeches, streamers, etc. that are successful here in the Yellowstone country of Wyoming but specific patterns would be of a great help.
I just want to help him have some good success with a flyrod

because he is about ready to give up on it. HELP!!!!
Thanks in advance for your

.
