I used to agree with Quick and opt for speed so long as I didn't sacrifice too much silence. Now, after a number of years shooting speedy bows with harsh draws my shoulders are paying the price and I now look more for a smoother draw.

As Quick mentioned technology has caught up and made speed bows much easier to shoot, but it has also caught up and made smooth bows a lot faster. So, I'll take a smooth draw with the speeds that I used to have on speed bows I'd have to pull hard through the entire cycle and enjoy my shooting a lot more.
