Tech-sights for Ruger 10-22

[x westie]

I want to install Tech sights on my Ruger 10-22, i would like some input from Ruger 10-22 shooters as comparing the TSR-100 with the dual leaf aperature, and the TSR-200 with the single elevation adjustable aperature.

The TSR200 seem to outsell the TRS100 by quite a bit, people seem to prefer the adjustable rear sight.

I bought the trs200 and really like the adjustment. Really well made.
