I have both from the same bowyer, and there is not much difference, in the two, which are both all bamboo.
Some string follow bows will feel as though they stack when drawing. IMO it is because there is little tension on the string for the first couple of inches, compared to a bow with setback. A straight limb is somewhere in between the two.
A bow with setback has a draw curve of say 20" to full draw, and a string follow may be 18" to full draw. Consequently, the string follow is increasing to the same draw weight in a shorter distance, which is more lbs/inch.
Bows with glass might be different from the same bowyer. The most important consideration is in the bow length, riser length, limb design and taper and width of the limb from fadeout to the string nocks. A bow with smaller tips and more taper might be faster, and smoother drawing for a given length bow. A rounded or flat handle and heavy tips will seem harsh in some bows.
Be sure to use an arrow that is around 10 x the bow wt. I think your right to try a few different bows to see what you like.
