Best setup for lightweight cycle touring with Ti road bike Should I use rack or trailer? Touring would be B &amp; B normally, but might involve some minimal-gear camping (no cooking) occasionally.

If a rack - what type is best? - there are no braze-ons for a rack, but the Ti frame should carry weight OK and the wheels are strong alloy with steel spokes. Would heel clearance be an issue?

If a trailer - is there a danger of cars pulling across behind and hitting the trailer? I also worry about jack-knifing on steep downhills, and being tempted to take more weight than the (Ultegra) brakes can stop.

Thanks.

PS I'm pretty light myself - about 65kg
I would avoid a trailer.

On rear rack you are going to have heel clearance issues.

It may seem extreme but get a front fork with braze-ons.  Braze-on on the inside and outside for really solid rack mounting - check out the Salsa Vaya.  Not going to cost you more than a trailer and ride a lot nicer.    

Also consider frame bags. Check out http://www.revelatedesigns.com/. See this set up http://moots.com/our-bike/cross/routt-45/overview/. You can put water bottle cages on the axles.
