I tie my own and highly recommend you do the same. You will save money in the long run (there is a short term investment in materials to overcome first), but more importantly your satisfaction with each fish you hook will increase exponentially as fish start taking your own ties.
HA HA HA HA HA HA HA my wife has a different opinion on fly tying saving money
Im finally now at the point where I only need a few odds and ends when it comes to materials. I still have nothing compared to what some guys I know have even though I have more materials in my house than you'll find at the Squamish fly shop
the wall is only salmon/steelhead materials. There is a giant tote in my closet with even more plus a massive tackle thing full with just trout materials which doubles as my "travel kit". The drawers are just flash material, rubber legs (squidro) and polar bear
