Look, I have had two and still have one. If someone offered me the 1200 bucks I had in it, I'd take it in a heartbeat.
Being younger than you my pupil dilates enough to watch reticles subtending 1/4" at 100 yards fade before the heavier versions do. It does not take me past dark...it may take you. Glasswise, the S&B possesses no low-light magic over its brethren.
S&B now offers a more competitive low light reticle in that model but unfortunately they won't change reticles in the Summit.
The wide reticle doesn't cut it for me in the S&B or the Leupold.
