HOw does it compare to a wicked? I am itching to get one and would like to know what i am getting into.
I don't have tons of saddle time on a P series, but a few things come to mind.
First, Ritcheys always feel shorter than the size so, for me, I miss the stretch and am always back over the saddle unless I size up. Stand-over gets compromised.
Again, in my experience, the people who really loved their P-series bikes tend to be average-sized or smaller, lighter than average weigh, all-heart-and-lung types with fantastic bike handling skills. It's much more finesse-styled geometry.
The Fat is far more forgiving of you being tired, a pedal masher or someone who wipes out. As you note, if you can't keep up on an uphill, chances are you could make up it going down on the Fat. Try doing that on a P-series with a tiller stem and roadish angles and you'll be in the bushes with a dented frame.
I have a WCS P21...
the ride is good, the bottom bracket is lower 11.5 inches, very stable. Top tube is more horizontal. I have had to find a jerk stem (more trajectory upward) to get the right riding position. P21 LOGIC tubes are super soft. Easy to dent. Very light, a little flexy but it hauls ass...and is very predictable. Fairly easy to warp/overtighten the seatpost clamping area.
If you can find one, and you have the cash, i would say it's hard to go wrong...
