On the subject of tyres, I've found the Marathon Plus's to be really heavy, whereas the Marathons (with out the plus bit) are a lot lighter (and cheaper!) and more comparable to my randos on the other bike, with pretty decent puncture resistance, but with the added bonus over randos of the reflective strip which I find makes a massive difference to visability. Also they're almost always on offer at BikePlus!
