Rob, I'm going to politely disagree with you, no hard feelings...
Back when Hill wrote his books, he was writing to the masses, and still using mostly unfiberglassed bows. He preferred longer bows and they fit him because of his size and draw and the durability of a longer unfiberglassed bow. His bow formula with reflex worked for a longer bow. He taught bowyers how to build his style of bows with these specs in mind. At that time, he preferred those specs......
fast forward to the 70's...John Schulz was building bows how he was taught, long and with much reflex, and his preferred bow was 68" for a 26" draw...but his bows at that time were heavily reflexed and the longer length kept them stable yet very fast shooters...but in the back of his mind, he remembers Hill tutelage about string follow bows, and he gradually changed his bowmaking to follow Hill's personal instruction. Schulz's personal bows became much shorter...the bow in his video is only 64", because he was departing from the radical reflex bows to a softer string follow style as per Hill's instruction. His bowmaking was modified to take advantage of Hill's preferences in bowdesign and modern materials like good fiberglass and his later bows built for Hill himself used this thinking....
fast forward to the 90's...Schulz is now only making all bamboo/wood bows following Hill's early bowmaking principles, but allowing for current technology and making short bows sized to the individual shooter. He shot bows as short as 62"...
I'm stating this to say that as time has progressed, the Hill style bows design as made by Hill and Schulz (his ace student) also progressed. If we make a static statement concerning Hill's or Schulz's bow preferences, we need to look at the time period and bow design that statement refers to, or we are in the wrong context of the statement.
Rob, You have stated numerous times that you have had a gaggle of Hill style longbows. I don't know how many you have now, but I wonder how many you've sold because they weren't 'right' for you....not in cosmetics, but in shooting characteristics. You've had a chance to specify how you like the bow to be made, and yet they still might not fit you. I've seen a photo of your bowform...in my opinion it is very much a target/recurve form. That is not a bad thing at all. It is YOUR form. However, I've seen way too many guys with a target/recurve form not be able to shoot a Hill style bow well, not because of the bow, but the style of shooting wasn't conducive. The Hill style bow has it's own nuances in shooting and it's more critical of those nuances than recurves or r/d bows are. Maybe the reason you've not found the holy grail of Hill style longbows is that your shooting style is more conducive to a r/d bow or recurve...that statement is not meant in a demeaning or derogatory way, nor does it reflect on your joy of holding and shooting a hill style longbow... it's just food for thought. Discussions like this help newbie Hill style longbow shooter think about their choices and what fits best for them.
