When you make your crease fly, make the front flat and allmost at 90 deg to the hook shank. This is not the usual look but what you will find is the ones with the front end leaning forward will sometimes roll ot the retrieve or even flip over and grab water when you go to pick it up on the back cast. Try it out both ways and see what you think. If you do a google search on imiges you will see all kinds of shapes. The one for me to prove best has been the flat face shape. Check out Joe Blado"s crease fly. Have fun with it and post some of your creations. Tight lines.
