Three David Miller longbows, 1-straight limb all bamboo, string follow, very mild, 66" 56# @ 27". 1-backed bamboo Hawk, string follow, 67" 57# @ 27", and a 1-backed bamboo Hawk with more string follow, 65 1/2" 60# @ 27".
All are extremely quiet, smooth with no handshock and good performance. The shorter bow with the most string follow will stack the last inch at 3#.
String follows do not require string silencers, and are as quiet as an R&D with them. They are not as fast as a 62" 54# @ 28' Purist Longbow (R&D) by Robertson Stykbow, but smoother and more quiet. They carry a very low string 5-3/4" with the feathers touching the rest.
They are only slightly smoother, and quieter than my Old Tom, glass 68" 64# @ 27" longbow with 1/2 inch backset. The latter is maybe faster, and just as accurate.
The disadvantages of any string follow is the sense that it stacks. It is possible because they are sooo smooth to start, very little tension on the string and therefore, they reach the peak weight in a shorter distance.
The other thing about all Bamboo, other laminated bows without glass, or self-bows is they are draw length specific, if it is made for a 26", or 27" draw, drawing it another 1 or 2 inches will eventually ruin the bow.
