Looking for recommendations for a serving tool.I would like to start making endless loop strings for some vintage recurves. There are a LOT of choices for serving tools, and I don't know how to chose one. Are they all pretty much the same?What do you look for? I had an expensive learning curve with fletching jigs, until I acquired a Bitzenburger, so I would rather buy a quality , lifetime tool, once, and bypass the rest. Is there a Gold Standard for servers? Thanks, Mike.
