Duritz, thanks for that and so quickly as well! hee hee, every thing you say is true, but remember that 1 thing remains true also : that trap HAS to repeat, so YES it cannot be done in the way you described, cos we aint got that much ball! but there is some variations that could fit the bill of people so inclined.
Needless to say I gave this one up long ago, NOT because it couldn't work but just because my balls have defininitly shrunk after many such tries?? hee hee , appologies in advance to our sister investors here!! hahah! (squeaky hee hee)

PS .Thought I'd better get this one in quick b4 post your dissappears, trading on dangerous ground there, but one has to wonder why?????
