Jake. Glad to see you are happy with your shooting.
One thing that we have to keep in the back of our heads as we journey thru any pass time, is what we want and expect out of it.
8" groups at 25 yards is pretty good, especially if you only shoot out to 15 to 20. We humans have a way of wanting more, wanting different, wanting better. We are hard wired for it. Can't help it.
This is where those choices come in, and I am not intoning that laziness is involved at any level, just choices.
For some, a certain thing is what they want, what they feel. For some, getting better is imperative, and that is great, but realize, that better and easier go hand in hand. We have invented more and more ways to get better. We make choices. Where do you / I draw the line ?
Longbow or recurve or compound or crossbow ? No "sight", point on, string walking / face walking, front sight, front and rear sight, level, release, stabilizer, telescopic sight, using a range finder.
Muzzle loader with flint lock, with percussion caps, with open sights, with telescopic sights, with in-line technology, with electronic ignition, with powder pellets and larger percussion caps.
Modern Rifle with open sights, rifle with telescopic sights? Lazer guided ? Rifle with no human interface, just guided by computer ?
All of these are improvements and make you a better shot, and with each of these we make our own choice. Go there.. or not. Why did we chose that ?
Gene said "there is no shame in aiming". In reality, we always aim, no matter which style of aiming you choose. Some use simple systems, some use elaborate systems, but we all aim.
I think all of these choices are deeply personal and should be made, not because of what everybody else thinks, but because of what you / I think. If you choose because of what the others say, you will never be truly happy with your choice.
I shot both ways in my life. I currently shoot split finger and "instinctive" (kinda). I do it that way because it feels best to me.
I also don't think that it matters to the equipment. (in going with this, why not shoot two under for less tiller issue and for ergonomics ?)
