Brilliant. Any mock up photos of each? Having difficulty picturing them, especially without rigorous research on the models, leathers and detailing (not sure if others feel the same and might be hesitant to join due to this).
6 is the minimum I believe. A guy was keen to organise this on Reddit's Goodyear Welt subreddit, along with the above mentioned boot in teak cordovan. If that's the colour you were after, join that one. ~3 were already keen on GYW. Also - what is Paul and friends?
