When I bought the bike I got Gear shift pro and not the Keyless, through choice. I have not regretted it, I'm an old Lad but still like to give it some welly, i.e. when coming up a slip road onto a Duel carriageway , if there is a lorry or something you can just open it up and slide in, over 4000 rpm it clicks in the next gear a treat. And on overtakes works well. In that respect I think it's safer, as you are past the overtake quicker, it changes in a 10th of a second. And as has been said you use it 100s of times a ride.
