If you cut your arrows to 29.5" and use a broadhead plus adapter weight of 150 according to the Stu calculator is a 49.5 pound spine. The calculator for the Howatt Hunter with a fast flight comes up with a spine requirement of 60 pounds. i think that may be heavy for that bow. I would bet that the 2016 with 150 grains up front would be better than something stiffer. It is not so difficult to add a something to the side plate if a 2016 is too soft, but it harder to get a shaft that is too stiff to behave. If your total point weight would be around 125 grains I would try the 1916 first.
