I’ve got the 8, 10 and 12.5. Impressed with all. Compared to tier 1 glass, the lower power Tracts perform better because of light gathering. All of the Tracts are the best buy I’ve ever found. IMO, you’ve got to spend 2.5x the money to better them. My 10s and 12.5 were on sale/or were demos which is how I rationalized the expenditures....:)
