I prefer to cut bow wood..........any time I get the chance to cut some. It is harder to get the bark off of winter-cut wood, but it's not usually that big of a deal. Winter cut wood has advantages, too, such as it doesn't seem to check and warp quite as bad. I would cut one, split it into quarters, peel the bark, and seal the ends with glue. Take one stave and rough it out to near-bow dimensions, and you can start working it in a few weeks. Like Jawge said, sapling bows are a good way to get your feet wet in bow making, too. A 2" hickory or hophornbeam sapling can make a surpisingly good bow.
