It's been very interesting hearing what other people think about this subject, and it seems that the gimmicked decks have got alot of support. If I'm honest I actually thought it would be the other way round. I think that I agree with what jing has just mentioned:
I think that if the situation allows you to use a trick deck, and that's the effect you want to create do it. I wouldn't carry more than one deck of cards doing a walk around gig, but if I was at home, and a friend said show us something, then I might grab a trick deck.
I think this probably sums up how I would think of myself using a trick deck, although I would explore every option I had before finally deciding to use one.
It does seem that people don't have the same view as I had when I posted this that the trick deck is just a short cut. My thought was that we should be good enough to not need these decks and that they are sort of breeding a lazy type of magician. This is not an insult, but it just makes me think that I'm sure there are a fair number of people out there who wouldn't ever try to explore other methods of trying to do an effect because they feel it's easier not to. I think this might lead down a bad road because in the end, you might end up sticking with the trick deck to get your desired outcome, but if you don't explore you may miss something that could make your trick great.
In my view I would use a gimmicked deck only if I found that to be the best method after exploring many others. I think back a few post to randy, where he says that with the gimmick you don't need to be worries about flashing a slight. This is a fair argument, In my oppinion, if we are out performing we should have worked and practiced to the point where your slights getting spotted aren't an issue anymore.
Again, just my little bit of input.
