The trick is to not put the tensioner arm into the chain until after you’ve bolted it on.

Taking into account everything, including the fact that it's easier to fiw a puncture on a 2 speed than it is on a 3 speed, I cam to the conclusion that 2 speed is the best compromise for me.
There will be a couple of times per year when I will regret that choice, but I will probably regret more often having the 3 speeder

The upgrade path from two speed to six speed is fairly straightforward, so worst case scenario you can do that.
