my personal view is that unless you are very tall and struggling with space on the deck, any of the smaller to mid sized decks will be fine (i.e. 29-32"). Some people don't like the swallow tails as they are "non functional" but I'd say that what looks pretty IS important - loving the look of your board will make you want to jump on it and get riding. Post some pics!

I'd be careful of C7 trucks in a bowl or ramp, as they can jacknife on you. As Graham says, CX are the recommended option...

Happy Birthday!!
