Fly Fishing Lines FAQ

Q: What types of fly lines do you sell?
A: Drift Outfitters carries fly lines for every fishing style and species — from delicate trout presentations to heavy saltwater setups. You’ll find floating, sinking, and intermediate lines, along with specialty tapers for Euro nymphing, spey casting, and warmwater fishing.

Q: How do I choose the right fly line for my rod?
A: Match the line weight to your rod weight (for example, a 5wt line for a 5wt rod). The type of fishing you do matters too — floating lines are best for dry flies, while sinking or sink-tip lines are ideal for streamers or deep-water presentations.

Q: What’s the difference between weight-forward and double-taper lines?
A: Weight-forward (WF) lines have their weight in the front for easier casting and distance, making them the most popular choice for most anglers. Double-taper (DT) lines offer smoother roll casts and can be reversed for extended use — great for traditional or delicate presentations, however many weight forward lines also offer these benefits, making DT lines less popular.

Q: Which fly line brands do you carry?
A: We stock leading brands RIO, Scientific Anglers, Airflo, and more. Each brand offers premium coatings, slick finishes, and tapers designed for maximum performance in both fresh and saltwater.

Q: How do I clean and maintain my fly line?
A: Rinse your line with warm, soapy water and dry it with a soft cloth to remove dirt and buildup. Use a fly line cleaner or dressing periodically to restore slickness and extend its lifespan. Proper care keeps your line floating high and casting smoothly.

Q: How often should I replace my fly line?
A: With proper cleaning and care, most fly lines last several seasons. However, if your line begins to crack, lose buoyancy, or feel sticky, it’s time for a replacement to maintain casting performance.

Abbas Fadhil Adam

Dope fly shop, crazy selection of flies including big topwater bass flies of all sorts, and big pike flies which are pretty hard to find in person. Chill staff, loads of inventory. I make a point to stop here every time I'm in Toronto!

Ryan Dawsone

This is the best fly fishing store I have frequented in my 30 year fly fishing experience. The owner Rob, store manager Chris and the rest of the team are very knowledgeable about products and local fly fishing locations. They will guide you towards best products for your needs, and will not try to upsell if a lower priced option is better for you...

Simon Chapman

If you are in the GTA Drift is the only fly shop you need. They have an insane amount of quality tying products, packs, waders, boots, rods and reels. They also have the best staff w/ a staggering knowledge base.
