A listener wants to know which vintage Orvis reel he should put on a small stream rod. Can you give me some tips on keeping the deer hair on top of the hook shank when tying Sparkle Duns? After making a cast with tight line nymphing, how do I tell when my point fly is on the bottom? Is a 6-weight rod strong enough for Labrador brook trout?
