My friend has the 7-35 and the M7 both with T3 retc and he and his shooting partner are looking to get rid of the NF and get another Steiner.
I am impressed with my Steiner no doubt, but am trying to sell to buy a TT.
It nvr ends.
I honestly would get the one with the better retc, which is why I got the M7, the MSR2 is a fantastic retc.
