It's not that hard, but there are lots of hints and tips that you won't find just anywhere. Good information goes a long way--for the retail price of one string (more or less, depending on where you get it), you can have a video at your disposal that can knock tons of time off the learning curve.
We (Joe Stark and myself) put all we could into "Doin' the Twist" because we couldn't find all that information anywhere else. It's broken down into 11 segments and is nearly two hours long. You won't find it on YouTube, not legally anyway.
Barring no disasters, in the next week or so 3 Rivers should be getting the very first shipment of "How to Build a Great Bowstring", featuring Rod Jenkins and yours truly. It covers things not found in DTT, and DTT has some things not in this one. We did our best to put decades of experience, along with thousands of strings worth of experience, into about 90 minutes of video. The video quality is excellent, thanks to the expertise of Traditional Vision Quest.
So.....soon you'll have at least a couple to choose from, if you decide to go that route.
