You can't go wrong with IOR. I have the 10x and couldn't be happier. Glass is better than the MK 4s I've used as well as a US Optics I have acess to. Built like a tank and have never needed re-zero in 3 years on a 6.5-284 shooting from 30 yards to 1300 yards with ALOT of dialing. The field of view blows varible power scopes away so the extra magnification never bothered me at close ranges. The 6x tactical would be my recommendation, the knobs are not huge and are covered and the Mp8 reticle is very precise and useful on running game. Using the reticle for a 6 mil lead and some dialing I hit 3 hogs on a dead run at 534, 547, and 573 in about 10 seconds. Call Val at Valdada optics, he'll give you a sales pitch and an excellent product. I think you will be very pleased.
