Cade says ” I have been messing around with hotspot Perdigons for a while now and didn’t want to be limited to just a hot spot for the collar and wanted something different for picky tailwater trout. I messed around with a few different materials but landed on Flex-Floss as it still allows the fly to be very durable, sink fast and adds some additional movement and vibration to the fly. I have fished these from picky Tailwater Brown Trout to aggressive backcountry Cutthroats and this fly gets the job done! “
