Nice looking worms. the segmentation looks great. i had the same thought as Dave, going so far down the bend of the hook might interfere with your hooking capability. Or it might end up rubbing or being pushed while a fish is hooked and damage the fly faster than it would if you started a little higher. Did you use superglue under the length of the fly to secure it all the way down the hook, or is it just tied in at the top and bottom? the dark thread underneath shows through well and makes for a nice contrasting hotspot. That's a good design and will definitely catch some fish.
