I have 2 of the sleeve TD's; one is 60#@27", 60inches long, the other is 53#@27, 64" long. The 60 incher was made in 1992 and has deep core limbs, the 64 incher was made in 2007 and has flatter shape limbs. They both are smooth shooters and the 60 inch is amazingly smooth for being a short, straight-end, no reflex/deflex type of bow. I actually prefer the deep-core design and wouldn't feel really handicapped if the 60" was the only bow I owned,although I normally prefer and shoot better with longer bows (64" to 66")
