i am about ready to plop some cash down for a nice bar bag, but as always, second thoughts plague me. i ruled out Ortlieb cuz it sounds like a pain to mount. Lone peak sounds ok, but there is only limited info here about them. Arkels sound great, except that they are a bit weighty. That said, i still think the Arkel is my number one choice. i just cannot decide on the size. i am leaning on getting the small bar bag, but i am not yet totally committed. For touring, do most of ya'll think that its size is adequate??? Thanks.
