Re: learning to cast, progress report
Sounds like great progress, but ease into the whole line pumping thing. I think what you're referring to is a technique called the single/double haul. Its a great way to increase line speed, control loop size and all sorts of wonderful things like this.
However, there's also alot of truth in the idea that the double haul is a way to throw your casting mistakes further. Its a wonderful thing to learn and have in your arsenal, but just make sure you're not putting a supercharger on an engine that hasn't had all the basic engineering bugs worked out yet.
