Ok, so I need to sort a double buggy, it needs to be pretty friendly to rough terrain. P&T seem to be the best option, but I'm buggered if I can see any real difference between most of their models! I've seen a good price second hand vibe - is this different from the explorer? Any comments would be most welcome, but especially those relating to ease of steering/ durability/ good over rough terrain. Thank you wise buggy users!!!
