Like already stated I found using coastal deer hair for small versions easier to tie with.
But I have also had good success with using less elk hair than what I thought I needed. After getting done I thought the wing looked sparce. But after fishing with it I realized that the fly remained quite fishable and visible with the sparcer wing.
Another thing I have done in the past:
After making a couple of loose wraps around the hair try spinning the bobbin. This will get the thread to stay twisted instead of flattening out against the hair. It will dig into the hair more thus gripping it better but will not cut through. I then spin the bobbin a little in the opposite direction just before I whip finish. Twisted thread seems to be stronger than untwisted thread.
This technique also gets the hair to flair a little more so that when you use less hair it appears to be a fuller silhouette.
