If you can get one, and then have to move it to get the other one, I would make sure you're skew setting is correct. I use a Supper Sat Buddy and I have no problems getting all 3 lined up. It's been a couple years since I used the bird dog, so I can't help you specifically there.
With the new 129 coming online, I would just put up the 1000.2, and tell customer service NLOS on eastern arc and they'll change it. Actually you don't even have to tell customer service you're doing it, but it's good for them to know what sats the customer is on, if they do some migration of channels in the future.
