This is good for Stage as well as parlor - even close-up.
The advantages over the BOND
gimmick is:
1) You have NO extra ring you have to "ring" in and out - you truly use just
borrowed rings.
2) No "fiddling with the Himber ring to open or close it. Sure, a good
performer can mask this well, but if you can avoid it, why not.
3) The audience never sees
an "EXTRA" ring you bring in and out.
While there are ways to almost always avoid the
audience realizing there is an extra ring in a stage performance why bother? Depending on the size
and position of the crowd in parlor magic, this could be an issue, and in close-up it ALWAYS is an
issue.
The advantages over the Himber Ring is:
1) It is more examinable while linked -
the issue in close-up and to an extent parlor, is they will notice you are ringing in and out
another ring
2) It is not as "angley" - although this really only applys in close up, and
possible parlor magic.
All in all, the effect is the same, but I will feel more comfortable
with this method the vast majority of the time.
I have used the Himber (or Stagg) ring,
and have yet to use this method, but I am very confident, and will probably be doing this effect a
lot more with the BOND method.
