Never had cruise control, until I got my 2015 deluxe. Never thought I would use it very much. Turns out, I use it way more than I thought I would. When I ride with other bikes that have a throttle lock, their bikes lose speed when going up hills, compared to the electronic cruise control, of the 6. So, if you plan to take rides with others, it may be something to consider. I DON'T ride the freeways, and still find the cruise a great option on 2 lane roads.
The cruise is great when you need both hands to do something like changing out your glasses from shaded to clear or vise versa. Even putting on sunscreen and of course if you want to travel a constant speed. If you prefer the black then that is the one. Remember it seems like well over half of all F6Bs shat show up for a get together are black, of course matt grey is not rare either, I preferred black at first but glad I got the grey for the cruise, the black pipes and the less common color. Either one should make you happy.
