I can give some thoughts on the difference between the Maestro (4-bar?) equipped Trance and Single Pivot Five, having spent a fair few months on each. Unfortunately I’m not smart enough to know what is down to the suspension and what is due to the various other differences, but here goes:
The Trance certainly gives a plusher ride. You can almost disregard the terrain and just focus on smoothly putting the power down. Where the Five will nip at your heels like an over-enthusiastic dog, the Trance is more like a magic carpet. Basically I’d say that the Trance is better 95% of the time and faster overall. The problem is that the 5% of the time that the Five is better is the 5% when you really appreciate it. I can get up a few technical climbs on the Five that I’ve never cleared on the Trance and coming down the Five gets fun at just the point where the Trance got scary. Since I don’t race and am just out for a bit of fun I’m happy to put up with the rougher feel most of the time for those few extra grins.
However, I am a very limited rider. It may well be that somebody with more skill would be more bothered by the shortcomings of the Five. Brake jack, for example, isn’t an issue when you are mincing down trails at my speed.
It’s also true that the Five relies much more on the shock (a Factory Kashima CTD-A unit on mine), but I like to fiddle and the shock is very handily placed for fiddling on the Five. Those who prefer to just set up a rear shock once and never touch it would probably be less impressed.
