Seige - I agree with most of what you say there, but I'm not totaly convinced by:-
It is a VERY big mistake to use every finger, because in real life, you just would not need to. Try THUMB, then MIDDLE.
I agree 100% with trying to mimic how you would do it without the TT, but my personal feeling is that without the TT you would probably just use the index finger.
So my next reasoning was that if you use the index finger, switch to thumb then switch back to index finger, (showing hand still empty) then this could look a little odd. Undue attention on why the sudden switch to the thumb.
by walking through the fingers. Middle, Index and thumb and back to index (showing the hand still empty) - then (imvho) I believe this to actually be a little more natural.
In saying that - I bow to your much greater experience and readily admit that I am still learning so much with the TT and in fact all aspects of magic.
Thats why places such as this are so fundamentally useful as discussions like this can take place.
I will have to try both methods with my "lovely assistant", the wife (she already knows about the TT) and see which ways looks more natural, although that isn't a great test as it would be difficult to say what looks most natural when you know full well neither way is natural.
