Ya the Warnes on my A-bolt have held the same zero for 14 years and have flown on a plane 4 times. Not gonna sweat the ones I already installed.All else being equal, I would rather have the steel Tally units (lets not get started on the Talley LW); however, I've used 20+ sets of Warnes without a single issue, and some had/have a ton of use and shooting on them, so I wouldn't fret the Warnes. And the Warnes fit a number of mounts vs Tally using a proprietary design.
Everyone I know really likes them.You have me talked into the Talleys for future mounts. Warne lists “Sintered Steel” which is powdered metal. There are some claims for vibration dampening benefits etc. but I don’t know how much of that is snake oil. I would rather have machined parts.
