I was owner of a FP1, now having huge trouble (different problems) with my 4 years old FP2. Therefore thinking about buying the FP3.
You mentionend the “new” size of the FP3: 15 mm longer than the FP2.
Questions:
Culd you get used to it by now? Or in which cases to you have problems with this aspect? Too large for some bags…? I would have problems to get the FP3 into the saddlebag of my bike 
Thanks for your feedback!
