Steve, I bought a couple of the new Cronus BTRs before our club's annual gun show last month - wasn't all that optimistic about chances of selling scopes of this quality/price level at this show, but you can't sell 'em if you don't show 'em, so... I've compared the newer BTR's reticle to that of the older original Cronus, and believe its slightly finer section would be an advantage when shooting very small targets (although I've not had any issues with the original reticle), and I like the slightly larger font for the numbers on the turrets (I've had trouble determining whether I had my elevation knob on zero or 9 with the smaller font of the original scopes in poor light). Haven't had one of the new BTRs outdoors to compare optical quality, so can't comment on that, though I'd like to hear other Cronus BTR owners' opinions of the glass quality. The glass of the original Cronus is good enough that it'd probably take some serious comparisons to detect any difference - or at least, that's my opinion.
The Ares scopes are new enough so that I don't have a lot of feedback or personal experience on how durable they're going to prove to be - have three of them on custom rifles I've built for my own use - Howa Mini in 6RAT, M700 in 223AI, M70 in 6x47L - and would like to put the one I have left in stock on another new M700 in 7-08 Improved 30*. I put them on these rifles to get more personal experience with them - and so far, they've all been good. But I'm really looking forward to getting the 34mm Ares scopes I pre-ordered - my feeling is that they're going to sell a lot of these scopes.
