As a ham-fisted newbie, perhaps I'm being a bit presumptuous here, but whilst it's nice to use Bicycles etc. (now I've got used to the 'looseness' of the deck,I love them), surely practising with 'cheapo' cards as well can't be a bad thing.
I say this as I'm betting that once people know you're on the handy side with card tricks, they'll want to see some, and whilst you may have your own deck in your pocket, if they wan't you to use their deck (to make sure you're not 'up to' anything), you can almost guarantee they won't be a premium deck. In the UK, you could probably lay a bet on their deck being smaller too (is this the 'bridge' size I keep seeing being referred to?).
See where I'm coming from? Whilst all those gaff decks are printed on bicycle stock, when it comes to using a straight deck, if you really want to prove your salt, then a borrowed deck is one of the best ways to prove your skill. I know most of the miserable swines in my local would be very suspicious if I only ever used my own cards.
Not that my skills are fit for public consumption just yet...
