I have never seen that scope, but had a SN-3 T-PAL for a while. Really liked it. no real complaints. Was heavy, but I knew that going in. Ended up swapping to a NF 3.5-15x50. Traded mil/mil for weight saving.
I'd like to have a look at a sn3 1.8-10 37mm, but I have a feeling a NF compact will beat it.
It sounds like I am a NF freak, but I am not. When I am buying, I find a vendor that has the 2 or 3 scopes that I am considering, and have a look through them, and mess with them.
