I have 2 66in string follow Hill Tembos (actually just sold one of them) and both have less string follow than a NM Shelton. One had about the same string follow as my Echo and the other a little more so they were not consistent, although the one with about a 1/4in more string follow had all lams on the back of the riser and the one with less had one lam on the belly.
Both are exceptional shooters, best Hills I have shot imho. The string follow bows in general are soft at the shot and very quiet. You may get 2-3 fps more from a backset limb profile bow, not a real practical difference. I am going to order a 68in Big 5 with the string follow limb profile.
As far as comparison the craftsmanship on the Echo and especially the Shelton is better but they all shoot great. The walnut limbs on the Echo have a little more thump than the bamboo limbs on the others.
