......You are right, my SDs are very clean. But, who needs 3 Patent Pendings? (LoL). One would be fine. And you are right, what could i possibly add to surpass my 6200? Another 3-6-9 dial? Why? Not needed...i have a 3-6-9 dial!!! Milsub? Well, plausibly, but that would not be a direction my collection has taken...
