It is very fast and responsive. It's like it is just as eager to go as I am, you know?

Sewing on the leather... It wasn't hard, but I don't know if it was easy. I'd say it was fun but tiring. The whole process took about 2,5 hours and went by without any incidents. I guess patience, a good eye and a steady hand is needed. The only really tricky part for me was to judge where to make the hole for the brake lever pin. I couldn't get it off the "ring". But the leather is so soft that you can get away with not being very precise. Just pull on it a bit, and it will obey you.
