I haven't used one, but after firing a couple of rifles with the replacements I'm inspired to do so.
TC built their rifles with high combs to allow scope use. Trouble for me is, that high comb knocks the holy snot out of my prominent cheek bone with heavy loads. More drop, as with a Lyman GPR for example, and I'm fine. The Pecatonica falls more in line with the drop of the Lyman.
That can be a good thing or a bad thing for you, depending on how you shoot. MY principal hunting pard HATES the Lyman because it doesn't support his particular head for stability in aiming. Just too low for him, while he loves the TC.
