I actually think the orange ones look awesome... but they would have clashed with the CF on my bike (j/k)
If the white ones didn't turn yellow with age I would have likely gotten those because I like being able to see fuel level. As it is I kind of meter my fuel by usually only filling one tank (then I know I have ~6 gallons = ~200 miles). I only fill them both when I need it (400+ mile range).
When people (non-motorcyclists) see my bike in person I think it can look a bit intimidating.. which can be bad when trying to make friends broken down in BFE
Maybe I just need two giant smilie face stickers; one for each side?
All that said.. if they came in blue I think I would have gotten blue
