TBH I would just go with a flipflop hub if you are unsure with what you want. I have a coaster wheel built up with a velosteel hub, it's on my wife's bike now but I have ridden it quite a few times myself. It's probably one of the nicer coaster hubs but also very heavy. The hub alone is close to 1000g which is more than some full rear wheels. When I bought my SE as a new rider I rode it completely SS then when I got my leader I built it up fixed. I've since sold my SE and ride my Leader fixed all the time. It took me a while to get comfortable with it as a newer rider but after a few weeks it becomes second nature. The only real way IMO is just to build a flip flop hub, you won't really know until you try
