With my first child on the way I don't think I can justify keeping my DH bike, so it looks like I will be going down the one bike with two sets of wheels route. The pitch is highly rated and looks like it will do everything I want, but I'm not quite sure on the sizing. The medium I tested felt pretty good, but left loads of seatpost showing at XC pedalling height, but on the next size up the TT is over an inch longer.
I'm currently on a Dialled Alpine Mk1 in the largest size which I like, but shows huge amounts of seatpost. I'm around 5'11", so how tall are you and what size pitch do you ride? Some people on here roll their eyes when the term 'chuckable' is used, but for messing around which most of my local riding consists of I prefer a bike I can move around on.
