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.
Here are some photos of the multi-S suspension if anyone is interested. Here is the front:
and here is the rear - several photos showing it taken apart and what it looks like put together. Basically I think this is an over-engineered polymer. Maybe I should try it again some time?
