Really??? Not that I put much merit in the whole discussion surrounding "planning" I do know it's nearly always referenced to frames with an amount of flexibility in the frame. An amount that is greater then typical. Yet here you A) are planning to tour with some weight. This is not where you want a rather flexible frame, especially when you have placed stability on the list. And B) The frame you have is not what I would call a particularly light weight or flexy one. Mountain bike frames with their large diameter tubes tend to be stiff for their size.

Sorry to sound like this but I feel you are focusing on what you want to believe in and not what will be. Andy
