Just to throw in, a lot of people I know with running contacts also train stopped contacts because sometimes you need both. Trkman lost some competitions because judges started setting up courses where running contacts put you at a huge disadvantage. The people (mostly Brits IIRC) who had both contacts on their dogs were able to have success.
Payton has 2o2o not because I need to catch up but because I want his contacts to be clear to the judge. I have seen plenty of contacts get called because the judge isn't sure. Don't make the judge question your contacts is what I have been told by multiple agility pals who are also judges... so I went 2o2o with him. Although I am going to re-train his a-frame to a running a-frame... and I may regret it... if he starts getting called even if he is in, I will probably switch back to 2o2o again... =P
