Hey brothers. I've been on the chanter about over a year now and I haven't thrown it across the room once ! I have recently told a fellow piper (my tutor) that I would buy his ABW pipes from him. My concern is that he plays a large bag because that's what he learned on and now he's used to it. He has told me though that most people don't use a large pipe bag but rather an elongated small or medium. My question to the pipers is: Should I take my measurements soon to get help sizing myself up to the proper bag for me, or, should I stick with a large bag and see if I can handle it ? I am an average athletic build dude. 5'10" / 165 lbs. / 32 yrs old
By the way- I haven't actually bought the set yet, although I am committed and not changing my mind, and have not had a chance to sit around just getting familiar with them. Any help ?

Side note: What the heck is the Bannatyne "INVERTED" pipe bag I saw on www.nwbagpipes.com ?
