A 66" would fit you well. The Wesley is ultra smooth, but there are many who think the extra lams of bamboo don't really help until you get into the 70# or greater range. For lighter weights, the Tembo with it's three lams of bamboo seem to be very popular, and provide plenty of both performance and smoothness. It is the foundation of my next custom order.
All of my Hills are bamboo combination bows, and I have not shot the all Osage, or all Locust bows. I do have an all Yew bow, which shoots well, but in my opinion isn't as smooth as the bamboo cored bows. My favorite is my custom Wesley, but I like the quickness of my Halfbreed, and the beauty of my Cheetah. Hard to beat the Juniper lams.
Several guys on the Hill Bug thread really like the string follow bows of the Tembo 3 bamboo lam variety. I spoke to Craig the other day and he was explaining that the string follow is max smoothness, where back set is max speed. He offers 3 different grip styles from straight to locator. Mine are all slight dish, which is a comfortable compromise for me.
His prices are all set on the number of lams, so the Tembo is the least expensive, and does all the same work. All the rest of his product line is 4 lams of varying woods, and then peaks with the 5 lam Wesley.
I shouldn't be speaking just of Craig's Hills. There are a LOT of very fine "Hill" style longbows out there, I can only offer opinion on the Howard Hill Archery line though.
There is plenty of help on here for the Hill style bows, as they definitely have a cult following, me included.
