Getting a Shrew Hill will be a tough chore ... But if you can score one do it!!!
I love mine, it is natural to shoot. 68 inches should do your draw length fine. This bow is very smooth, incredibly smooth on draw and release, even for a string follow, it is delightfully smooth. It is also one of the most "intuitive" bows I have ever shot. Lastly mine weighs about 16 ounces, yet yields surprising performance. I have shot through a buck @ 17 yards, as well as a 250 pound wild boar, clean through both with woodies.
The Shrew Hill is a magnificent bow.
