I have the version with titanium rails but the body is the same (and the weight isn't too far off).
You can see why this saddle had been around for so long - it's broad enough to be comfortable without being bulky, it has nice firm padding, very slight give through the body, and of course it looks great.
I replaced a minimalist Specialized Toupe' with this saddle and I found them surprisingly similar, though the Regal is slightly more comfortable.
I wouldn't hesitate to use this saddle in competition.
One proviso: the sides of this saddle come down and completely cover the rails, so it is NOT compatible with a side-adjust seatpost designed for ultra-modern saddles with exposed rails. You need a post that adjusts from the bottom.
