Jeff, I really like my 2.5x8's and bought my first vxIII 3.5x10, and liked the extra light, I really haven't had to many issues with eye relief with them, I still have a 2.5x8 on my 270 win and am very happy with it, but I do prefer more magnification on my two 300 Win mags for LR shooting, just bought a 4.5x14 LR with an M1 elev turrett to play with, my buddy just bought a vx3 3.5x10 with CDS so I will have a chance to compare them in hunting situation this fall but so far I could like both,and I do like the low profile of the CDS if all you need is one revolution of the dial!
