Thanks for responding, and your clear descriptions.
I'm not very good at searching on this site. Before posting, I searched on trekking bars, but searched "Entire Posts." This got a load of mostly irrelevant stuff, that was very time consuming and unproductive to dig through. So, instead of giving you a list of what I've found, I'll give a search method:
- Advanced Search
- Keywords: trekking (or butterfly)
- Search Titles Only
- All Open Forums (or Touring, etc.)
That got a whole pile of great threads showing pictures, giving descriptions, and discussions. I agree. My post was pretty redundant.


This method will only work if people are likely to put the keyword in the title. For instance, if looking for information on touring with Mavic EX721 rims, searching on titles won't net much.
