Caught 5 fish in 5 casts at Deckers!

Love the chocolate thunder from Ascent. I always appreciate how well made these flies are especially because of the price. I fish mainly 11 mile canyon and Deckers and every time I go the chocolate thunder does well. Thanks!
A Decker must have

A perfect winter fly on the South Platte and the North Platte.
Magnet for Browns
Posted by kevin schneider on 23rd May 2019
I fish the "Driftless" Trout Region in the Midwest. I used these flies while fishing the Canyon at Decker's Colorado and caught a 22" Brown on a size #22 Chocolate Thunder. I had a few left over and I started using them in the Driftless. I don't leave home without these in my fly box anymore. They are like a magnet for Browns no matter where you fly fish in the world.

Don't leave home without them. The most productive emerger in my box.
A MUST have in Deckers/Cheesman
Posted by Michael Lapham on 31st Oct 2016
This fly is a must have for anyone fishing the South Platte, and especially in the Deckers/Cheesman Canyon waters. I have had a ton of success using the Ascent specific Chocolate Thunder (#22), really a must own for anyone fishing in that area.
