That is not what I meant by the casting comment. Just saying I don't do it that well or technically sound. I have just started with the two handers so I'll learn and get the casts down sometime.
I really like the sound of your stepped down ladder system sink tip. I am definitely going to give it a go. What material do you use to construct it or do you buy several shooting heads and then chop them up? If so do you prefer going a line weight up down or the same for the tips?
