I'm on my 2nd Turbo and have seen many a Turbo on other bikes. One thing I've noticed is that the padding firmness has been a bit different on other Turbos I've seen vs. ones I've owned. That is to say, they usually have more give whereas mine have been very, very firm. Is this because different year Turbo's had different hardnesses, or is it more on account of them breaking in over time, like Brooks do?
I've been running a Turbomatic II for a year and it seems, atleast to me, that it's gotten softer since I first owned it. Can't say for sure though. I haven't ridden either of my Turbos for anywhere near that long to know though (the second one I actually just picked up the other day and have yet to mount it).
