Wow, that was so too much that I can't even begin to describe.

Read the reviews, examine your bank account, and--most importantly--get in touch with them and see the shop floor. They'll be happy to answer your questions as to why you should or should not get an IF while you walk around and see them in action

In my opinion, custom is really for three things: building a bike for someone with unusual proportions, building a bike with unusual features, or just the luxury of having a bike that was custom built to your exact specifications by a cool dude(s) (or dudette(s)).

They're all valid reasons. Me, I'm having one done for #2 with a substantial sprinkling of #3. (Not IF.)

PS: some BF nerds visited IF in August, this is what we saw. http://www.flickr.com/photos/trevors/sets/1039189/
