GTI Caddis

The GTI Caddis is a fly I have had great luck with in the past. I have used this pattern for a long time. I found it many years ago when fishing up in Colorado, and found that its the perfect mix of flash to grab the trouts attention, but also life like enough that the fish dont get spooked when they get close.

Lance Egan is the original tier of this fly and actually has made quite a few different patterns that seem to always hold a place in my boxes, especially when fishing in Colorado and the surrounding areas. I believe Egan is from Utah, which makes sense since thats the next state over. I have also had good luck with this fly in other regions as well. California, Texas, and New Mexico are a few places Ive fished this pattern. I have quite a few acquaintances in many other states around the US, like the north west, north east and even central. Ive heard of them having great luck as well with this pattern in those areas. It really just works well.

While not the easiest fly in the world to tie, once you get the hang of it, it can be tied fairly quickly. The only difficult part I find is the casing, and getting it just right in the beginning of the mono tie down. The first few wraps of mono over the case tend to get frustrating at times. However with practice you will find this to get easier and easier.

Lance has said in some videos that he finds this color combo to be the best he has found. I tend to agree with him. I love the summer duck back, with the light olive body. However I have had good luck with some other color combos. If your caddis are more of a tan, try a tan body with a lighter case. Experiment for your local area and see what works best.

As you all know, I work closely with both and Both of these shops have offered every one of my subscribers a discount. So go to their shops, and type in "McFly" at checkout for 15% off of anything you buy on their sites. The hooks risen sells are just as strong, if not more strong than the ones I used today in the video. But priced much more reasonably. So definitely check them out.

Long story longer

The Global FlyFisher has been online since the mid-90's and has been free to access for everybody since day one – and will stay free for as long as I run it.
But that doesn't mean that it's free to run.
It costs money to drive a large site like this.
