I plan on it. I just didn't get it before hunting started last year. I would imagine with the ME I would probably be able to quit packing the ATX eyepiece? Maybe not though.
Dont know how well it would substitute the ATX eyepiece because I dont have the BTX. At least you would have 2 mag settings to use instead of one. With 70% increase in magnification, you will surely be able to discern animals much better at extended ranges.
