Building a long barrel muzzleloader (42") 54 cal.

The geometry of the stock puts the breech end about 5" from my eyes.

I'm using this sight on the rear:

1st off, the sight dimensions would nearly work out if the base leaf is set at 100 yards, it would put the peep window on the flip up almost dead on at 200.

2nd off, I am far sighted like hell.

How far from my old eye should I dovetail this baby in?

All things considered, what should I build/buy for a front sight?

I'm partial to hoods or globes on my front sights. Especially like the ability to swap inserts, but could make a custom blade, or for that matter, a custom insert on the globe.
