I m sure some of our more knowledgable will chime in here soon, but for me -- i use convertable Camptown Harness, (i use one of the girls as single as well) but have breast color style for them - they've had no problem. My carriage is a flyer, so attachments for traces are not super-low -- if yours are you migt want to think about trace carriers as I shudder to think about one of them getting a leg over. i like to hae breeching on, as I might be slow to brake for them, & think they can brake for us on mild hills, ect. I know that many people go without however. nancy in NH _________________________________________________________ To Unsubscribe, change to Digest or Vacation mode go to: http://www.drivingpairs.com/dpmem.html `````````````````````````````````````````````````````````
