Just looked at the Strada on ebay. I didn't get very much less for my Vogue, and I have to say, of all the treeless that I had - Freeform, Barefoot and Vogue, the Vogue was my least favourite.
It caused pressure points, which meant I had to use a suber pad, which was fine, but meant I was unbelievably perched.
For even half the price, I would not rate the Vogue. Everyone said it pushed my leg far too far back, and with having to be perched as well it was a nightmare.
I think Heather Moffetts seatsavers are wonderful, but not sure what she was thinking about with the Vogue. Even in her book there are pictures where she says her leg is far too back, but she blames it on her age. Oddly, once I had a Black Country working hunter saddle, which was £280 and second hand, everyone says what a wonderful seat and leg position I have.
Will be interesting to see if the Strada goes for that or more.
