Thanks for the tip, but I seem to be prone to eye fatigue when using one eye, at least during extended sessions at the spotting scope or rifle scope. I just gotta be aware of IP distance. Got all in a lather about getting the Yosemite's and before that Meade Safari Pro's and before that the 8.5x42 Audubon's (you can tell I'm a Porro guy?). Tons of good glass out there, but many of the Asian designs aren't concerned with the small percentage of folks on the high end of IP distance. Euro designs tend to accommodate us. Yea, I'm a slow learner.
