I'm not sure I know what you mean. I know there were rifles (not smoothbores) during the French & Indian War. The Pennsylvania/Kentucky rifle was around during that period...that's when it really got it's start, or just after.
I know it was not the "Golden Age" of Kentucky rifles, but they were not all smoothbores during the French & Indian War.
There are references to rifles in the American Colonies as early as the late 17th century, however, those early rifles were not signed or dated, nor are they known to have survived. The earliest signed and dated rifle known is the John Schriet rifle, dated 1761, other than that, what a rifle might have looked like and what kind of buttplate, how wide and deep; what the lock and sideplate might have looked like, what the triggerguard might have looked like, and how those components were put together, is anyone's guess.
Generally speaking, early rifles of that period were much more robust, with thick, massive stocks and heavy barrels, unlike the light, slim guns of the Golden Age.
Yes, there were a comparatively very few rifles in existence during the F&I period, but there are no known surviving examples of those rifles, so we don't know what they looked like.
Moreover, there were relatively few rifles in use during the F&I period. Some people seem to think that there were rifles behind every bush and tree, but even during the Rev War period, rifles were comparatively rare outside of western PA/VA/NC regions.
IMHO, anyone who claims to know what a rifle of the F&I period looked like is whistling into the wind. IMHO, anyone who claims to know what a pre- Rev War rifle looked like, is whistling into the wind, though there are a number of unsigned, undated rifles that COULD date to the early 1770s.
IMHO, comparing dating and research, to what modern builders claim to be early rifles is like comparing a Model T Ford to a 1970s vintage Chevelle SS. A vast majority of the rifles being made today, that are claimed to be "early", are nothing more than SS Chevelle's painted to look like Model T's.
I suggest doing a little research, on your own, to see what has survived and what dates are attributed to them. Then find a builder who is straight up, with you, about "early guns".
A good place to start is the American Historical Services page.

Another good site.

Then you might want to find copies of
Rifles of Colonial America VOL 1 and 2. Your local library might have them, or should be able to get them, if you don't want to buy them.
I suspect that your builder is suggesting a single set trigger to give you the advantage of a set trigger, with the appearance of a simple trigger.
IMHO, based on research, set triggers, of any kind, are rare on American rifles of the Rev War and earlier periods...and single set triggers even more rare.
If the builder knows what he is doing, a simple trigger will give a light trigger pull with a real nice let off and little creep.
God bless
