I agree with your points about the legs, they are a bit tighter to adjust initially but I found after some use they become very easy to set. I also found they locked very uniformly, just took me a while to get used to them. Perhaps give them a try for a while and see if they improve, the ones I used in Namibia worked great. I had Stoney Points with me and they broke do to the rough bouncing around in the back of the Toyota, the Bogs took the beating better. One thing I suggest, the rubber tips on the end of each leg do not stay in place and disappear too easily. Not too big of a deal since the steel tips work well in the field. I might place a dab of glue into the rubber tips to keep them from falling off since I like using the legs with the rubber ends.
I also get annoyed when I pull the legs out too far and they pop out but they return easily into place and no damage is done. Your points are well taken but I would give them a chance, I found that the more I used them the better they worked for me. They offered a lot of confidence when I was shooting from blinds.
I believe the best prices for that scope are right around 500 dollars, saw them being sold for that by someone on SnipersHide I believe. They need more elevation, mine have about 40-45 moa only. If you can zero the scope so the 100 yard zero is down at the bottom of the range you can get pretty long with the turrets but more would be better. The scope is working very well tho, returns accurately and the turrets are nice and crisp. I like this scope, just would have liked to see it with 70 or more moa of up and down.
