I have the Pedersoli Soule sight on my Sharps with the Pedersoli Globe Sharps front sight and they are OK.

Taylor has the Soule sight sold by Buffalo Arms (C-Sharps or something) and it is of higher quality (& cost) than the Pedersoli sight, along with the spirit level aperture front sight. Seems to me those two sights of his came to around $1,500.00. The Hadley adjustable disk is a really nice addition to the Staff.
