If you want tight deer hair you should be stacking and packing, not spinning.
Pat Cohen as mentioned earlier can explain some of the better techniques.
You also need a heavy duty packer, Cohen makes an excellent one called the fugly packer, but these tools can be made at home with little effort. I've made small packers but bought a large one of his because it was quicker and easier.
X2 on GSP is a must, also you need a quality vise, you don't want the hook shifting around with the pressure you'll be needing to apply to pack the hair up the shank to get it right.
Happy Tying, good luck.
