OK, so as a new Xootr Swift owner, can anyone explain / recommend....

1) A good rack?
2) How to carry my Topeak Road Morph pump, if I don't leave the rack on?
3) How to carry a 2nd water bottle, if I don't leave the rack on?
4) Does the ride feel any rougher with Marathon 100psi tires, compared to the 65psi Kenda tires?

I'm using my Twofish removable cage on the handlepost, and that's working out pretty well so far. But if I'm going for more than an hour, I like to ride with 2 bottles -- one water, one energy drink, hence 3).
