Please don't take it the wrong way, but I hate full suspension - ONLY for road/commuting (It still looks nice tho
).
If I was in the habit (like some workmates) of zooming around forests and over hills at weekends it would be great, but for road work and commuting I found the weight alone was bad enough (bike that is) as well as rolling resistance added to the loss of torque thrugh the suspension when pedalling.
That's why I got a road bike and a hybrid on the Cycle to Work scheme.
Looks like your bike also has knobbly tyres! - Changing to road tyres (no knobbles) would reduce rolling resistance and i possibly torquing the suspension up a bit to reduce power loss.
Anyway, that's just my opinion
