Here's a trick I learned with the Alberto...
Pinch a removable splitshot onto the braid end and then spin it around the doubled leader to form your wraps. It is super quick and forms very tight wraps. Then, instead of sticking the tag end through the leader loop to finish the knot, figure-eight it. That gives the wraps a much better buffer against sliding off the looped end, and absolutely keeps the tag end from slipping out.
Finally, a drop of super glue keeps the knot from fraying as it goes through the guides.
