Hey, Brian: Thanks for all the content to review on your site link. I think the S2 is a great compromise system in the MF category: not too big, fine optics, and the of-a-piece design rather than segments to be fitted together, resulting in better sealing. If or when you decide to expand your report or submit it to another forum or blog, take a couple of minutes and subject it to a spelling/grammar check to clean things up for a more professional presentation. Meanwhile, a lot of us envy your time handling this iconic system. Congratulations.
