I only have a bit over 1000 hours in the Buff, and I can tell you AR is not easy. Especially when you are on the boom for 20+ minutes to get a 100K onload. For us at least, AR was not admin. With anything else, a good Buff pilot behind the tanker will make it easy, however ask the boomers what a Buff looks like behind the boom on with a brand new Buff AC on upgrade ride #1 trying to hook up.
