Not ridden one, but I get the impression a Blue Pig is a fairly different ride to a 456. A bit like a 456 in steroids, in that it’s designed for steep and technical terrain, but is maybe less into flat/XCing. May influnce your decision?
I wasn’t aware that the Pig was supposed to be more compliant though. Tyres/tyre pressure/seatpost are obvious points to look at too.
