Depending upon what you like, I suggest you also consider a move in the other direction - assuming you have the 8 oz. twill fabric from Bujin. I used to have one of those, and this time I 'downgraded' to the cheaper 5 oz. duck and I find it much more comfortable and less cumbersome to train in. Those heavy cotton ones look cool, but - as they are significantly thicker and heavier than the 8oz. stuff - I can't imagine I would enjoy wearing one. It seems like it would feel like training in a snowmobile suit. The same goes for those wide-ass Bujin obi, too. Then again, I tie my hakama differently from everyone else I know, and like those stiff gi tops that most people can't stand as well...
