investing in a good strap helps. if you, like most of us, don't have the money to spend on Moody straps which cost about $200 or so, get a good Levy's strap from Davis. likely to cost you about $50 or lesser. i have a very comfortable Godin strap from Ranking which cost me $65 from Ranking. makes my monster of a Warwick seem very featherweight.
remember, it should just be WIDE, it should also be well padded.
