For the rear I prefer the standard shock as I am not sure there is any suspension in the multi-s shock rear. Nada. Nothing. Feels hard as a rock
I think you did well with the multi-s, which does not reduce the amount of travel like the colour+ does. The only downside is the varying pitch spring. The ideal solution is to get a spring for your weight. The varying pitch version caters to a wide range of weights at the cost of reduced travel.

Regarding the bobbing, this is a very interesting question. I puzzled a long while where the energy might be going when you stand on the pedals. I worked out it actually goes back into pedalling. The effect of front suspension is to spread the bounce produced by the body going up and down over a pedal stroke. Some may be lost but I think most is recycled. Riders think it feels lossy but the reality is less loss than thought. If there is significant damping in the suspension, then some more is lost.
