LaCamper,
If we can hook up, I'll gladly let you try/look thru that Weaver.
Got a three gun coming up in Biloxi the third Saturday of the month if your interested.
Next Sat is the Biloxi 3-gun. 98% sure I am going. Shooting an IPSC handgun match in Vacherie tomorrow if your interested. We have 5 fairly quick stages and it should go pretty quick.
I have never had to use my dots in harsh weather so I cannot comment on that. Just going by looks, an Aimpoint looks very rugged/weather resistant and that would be my personal choice in a dot type setup.
