Hey Mr. Ducksterfellow
you may ALREADY be hauling on your foward cast, many folks do without noticing. The timing necessary for the double haul is more specific & a bit tougher. HOWEVER, lots of practice, preferably with someone that is experienced to watch & correct your casting stroke, would be beneficial to you. Timing is everything here.
It's like patting your head & rubbing your tummy... it can be done, it's easy once you get it BUT until then.... you just feel like a fool.
Don't worry you'll get it... travel a little further east & I'd be happy to help.
Later,
Peter
