Have you a source for a Bald Eagle? That's the catch with them -- that is, they are hard if not impossible to find for sale in Canada. On the other hand, the Caldwell Rock BR is available.
Over on RFC, the guys generally favour the Bald Eagle. I have one and its elevation and windage adjustments seem to be finer than those on the Caldwell, which I also have. Having only recently got the Bald Eagle, I have more experience with the Caldwell and have no complaints with it. It has served me very well shooting from the bench with a variety of rifles.
