As said above,
A good magic trick does not NEED knuckle busting sleights or underground passes.
A good magic trick is one that works. Period. If you can entertain with a magic trick and perform it as intended, then its a good trick.
I have used gaffs many many times and have gotten the greatest of reactions ever.
Sure some sleights can do the same thing as gaffs/ gimmicks can, but sometimes, I ask myself "why bother?" If I need to practice one sleight for weeks just to perform a trick, when there is a easier solution, why not choose it?
I do keep practising my sleights/ moves, but still use gimmicks very often.
Gimmicks/Gaffs are an easier way, but they do not symbolise a novice.
There are also some gaffs which the tricks fails without. For example, show me a gimmickless/ gaffless Distortion. Or how bout an impromptu anniversary waltz?
Sleights give you the awesome feeling of accomplishment when you master a move, gaffs give you the feeling of "holy crap that was easy". I practice shifts and controls till my hands hurt, but still love those gimmicks/ gaffs.
Get what were saying?
Gaffs being a amateur's solution to everything is a horrible misconception. Get over it.
