I have one if its the 2nd gen T-Bird your talking about,, I'm normally a 27" draw but I have drew mine back to 29" with no stacking. I think with its design and Jay making one to draw to 31" there wouldn't be a problem my bow is 63". as far as the bow itself it shoots very nice has a nice comfortable grip, its pretty fast but I don't chrono. the bow stands out in the crowd mines is all Yew and glows in the sunlight,, everyone wants to check it out and shoot it because there's just not many around.. I had mine signed by Glenn St. Charles and he wrote happy hunting which meant a lot because Fred bear autographed a book for my father and he wrote that same thing. but the bow is nice and I would buy another if I heard Jay was going to stop making them.
