I started SS for the same reason a few years back, ie, I was curious. I also got fed up with destroying geartrains in mud.
I ride both now but a lot of riding is on SS, I really enjoy it. As above, terrain is very important – around my way there are (sadly) no really long hills to climb, which does mean that it is very well suited to SS. Surprisingly, I am often faster on any given stretch on the SS, partly I think because it makes me ride with much more momentum.
I found that I took to it from the word go, I think because my riding style has always been out of the saddle. Like someone above, I can’t stand spinning away.
Give it a go.
