Hopefully TT is better than Schmidt when it comes to actually getting product out from the time they announce. If you're looking at a TT525P vs a ZC527 then I can see the draw as they are both pretty close with 5-25 and 5-27x respectively; however, TT doesn't have anything like the ZC420 which makes it unique. I put in a pre-order for both the ZC527 and ZC420 but its the ZC420 that I'm most intrigued with as I'm very happy with my Minox ZP5 5-25 with MR4 reticle, I may end up cancelling my order for the ZC527 just not sure yet.
