That specialized langster looks like it would be fun to ride.
If you have flip flop hubs you might try fixed again.
It is not too scary with brakes once you get used to the feel of it. The first time I flipped back to ss from fixed after a few years I crashed. I just slowed my cadence thinking I would slow down, and crashed right into the runner I was riding with. It took a bit to get used to the whole coasting thing again.
now I try to do both occasionally so I don’t lose the feel and habit.
