I started with 68" ASL's and over the last year or two I've really seem to like 66" as well. Kinda the sweet spot for me also. Who knows. Maybe it's in our heads

I have read numerous times the quote by Howard Hill that "all things being equal a bow with string follow will be more accurate".

Has anyone had any experience comparing a string follow with an otherwise equal backset or neutral longbow?

I dunno.  I've shot them all, and can't say as I've proven one more accurate than the other. If I do my part, they all do theirs.  I do like the draw force curve on the string follow a bit more though.  It starts out gentler and builds weight quicker toward the end of the draw. Stephen Graf, author of The American Longbow) and I think Nate Steen as well have offered the explanation that one's muscle/skeletal positioning is not as good in the beginning to handle the draw weight (where it is greater with a set back design vis-a-vis a string follow) as it is toward the end of the draw. Because there is less recoil at the end of the shot with a string follow, I also find them more comfortable to shoot.  Whether any of this leads to greater accuracy, I'm not sure, but a string follow is my preferred ASL type.   

I have a separate post going showing off my new Bivouac - Hill Jack, but I figured it also deserved a spot on the HH thread.  Jim and Georgia really do make a proper Hill Style longbow. I am enjoying shooting it in my side yard for now, but I believe it will be my go-to bow for whitetail this Fall.

Congrats on the new bow Burnsie.  I hope it brings you luck this fall.  I'm a fan of brown glass.  I think it's good luck.  Brown glass leads to brown gravy!

Well, the bug still lives. A bit of backstory, I have since the early to mid eighties always preferred the longbow for bow hunting, as I aged (72 this year) I found I simply could not handle the 60-65# draw weights of my longbows. So for the past several years I turned to shooting one of my old mag handled Bear takedowns.

I recently found a Howard Hill Wesley Special 50# @27" in beautiful condition, at 62" I wish it was a bit longer but for my 26" draw it will work fine. I look forward to the fall season, my 55th.
