That makes sense, my only problem with finding a perfect scope is I won’t have anything to complain about. More importantly I won’t have that as an excuse, no excuses is a rather uncomfortable situation IMHO.
That being said! I think you mentioned you are in HFT class and interestingly it makes scope choices rather difficult due to the constraints of 14x magnification especially when it comes to ranging to put it mildly as a self proclaimed scope snob. Your list of wishes aligns with my selection criteria very closely.
Here is my list for HFT scope selection:
1. FFP, since I use ballistic calculator having FFP saves a lot of confusion and headache.
2. 16x-20x MAX. Due to FFP changes the reticle size 16-20x FFP at 14x gives most usable reticle size. Also scopes range better at or near the max magnification
3. Biggest objective lens possible, most at 40-50 but 56mm would be better. Bigger the objective lens the narrower the depth of field and better at ranging. This aligns with your S3 base as it has unusually large objective lens for the main tube size and magnification but glass is on par with coke bottle. Lower magnification(below 20x) almost never comes with 56mm objective lens, which is why I think getting the “perfect” HFT scope to my liking is almost impossible or at least VERY expensive.
For me in HFT the rest of your list like turrets are personal preference as you don’t touch them. In the lower price point I found the old element helix 6-24 does an admirable job especially at the price point. On the high end the S6 might work but MOA only right now. The new element titan 3-18 might work out well too, but haven’t had the chance to try one but I’m tempted to for other reasons.
Lastly, the problem with high end scopes is they are not made for this quirky requirement of HFT use case and have way too much magnifications. Even looking at March’s and other tier 1 scopes at north of $4000 price point, I still can’t pick one to use for HFT. Which makes a perfectly awesome excuse for me and my wallet, what did they say about the journey vs the destination again?
