I like my TMR, it works. Also, try to get a front focal scope. I didn't think the 4.5-14 was offered as such. With a front focal scope you don't have to be at a specific power for the angles to be accurate.
EDIT: Yep, they only have front focal planes offered on 63055, 64665, 60035, and 60030. (Link
) 64665 is a new product too.
