I tried using the 510 at one point. It was a lot like using tinder. *swipe* *swipe* *swipe* *swipe* *swipe* *swipe* *swipe* *swipe* *swipe* *swipe* *finally does what you want*

and yea, I guess 500 it is then.. I'll just go off of RPE whenever I decide to try out new routes. nbd..

It would be awesome if they can make the 500 more customizable..
