depends how stubborn you are really.
hills, even the really steep ones, are pretty much about the balance rather than the grunt (if you can get up in the middle ring regardless of which gear at the back, you CAN SS it) and with a bit of determination you can get up most things. The flip side is slower on the flats and on the downs.
I tend to do SS by myself in the autumn/winter, when a) conditions mean that speed is not an issue, b) you’re not constantly spinning like a loon trying to keep up with your geared mates, c) its maintenance free-(ish) winter MTB and d) you’ll be fit for when spring rolls around, and you’re re-geared.
It’s fun, a different challenge, can make you think about MTB in a whole new way, and people that don’t know ‘owt will be impressed. Girls knickers literally fall off at the mention of it (true story)
