I was thinking of getting my Float R Pushed along with a service recently so I phoned TFT, and it happened that the guy I spoke to had a Trance with a Pushed shock and said it was worth it.
He was right too, it's a great improvement – even though I was happy with the performance before.
He said it would feel like the bike had more travel, but that's not really how I'd describe it.
It seems to prop me up better (a bit like a coil shock), and then not plunge through the stroke so quickly – but stays supple throughout the travel.
Seems to deal with multiple fast hits (such as root sections) better, in that I can feel less going on underneath me in terms of suspension action.
If anything I'd say it makes my 4in Trance feel like a 4in travel bike (but one with really great suspension) – because it sometimes felt like a longer travel bike before.
I've waffled a bit, but I hope that helps anyway.
