Lolol! I'll play devil's advocate and tell you why sometimes speed is fun. Even I sometimes like to use 123 scenars in my 260 because they go 3000 or so and are lasers inside of 700-800 or so. They just seem to hit everything I aim at. There is a thrill in that, I admit.
Most of the time, I'm running 136g Scenars at a relatively sedate 2750 because that is just such a consistent node for that cartridge and does really well even past 1200. But like you said, it gets pretty hard to see impacts at that point.
I went down the Valkyrie rabbit hole after a shooting buddy said that we should build a rifle for it, each of us. I hadn't really been paying any attention to it before then, but started looking into it and really liked the idea of building a precision AR for myself that would allow me to use the small AR action as something different and fun.
For me, it turned out pretty good like I had thought it would and is providing that fun change of pace from my very heavy match rifle. Meantime, my buddy bought a new house and hasn't had the time nor money to build one.
I think that it makes for a decent mid-size varmint rifle too.
So, long rambling comments concluding, I think that you first need to decide what it is that you think that you want. For both of us, it wasn't/isn't about need as much as wanting something different to play with. What is it that you think would float your boat right now?
