We use a free swinging hook method, so line through then a small piece of slim plastic tubing goes tie your knot on the hook then slide the plastic over the knot and eye of the hook, the fly slides down to the hook and fishes incredibly well with out the fixed hook steering the fly, also helps a bit with the balance less drooping at the rear of the fly especially when you tie them without bodies or short bodies like this, also means when a fish takes the hook and fly are independent so better landing ratio too.
