Well considering your draw weight, and bow style I think the Magnus Stinger would be an outstanding choice. They fly great, are durable, sharp out of the package, and penetrate very well. I belive the magnus stinger is the perfect broadhead for those with lower draw weights or someone wanting the maximum amout of penetration. I will be using them myself this year as I belive they are the best new broadhead of the year, and I want to see how they do on game first hand. Other goo magnus choices are the screw in 100 grn head. It is larger than the stinger, and you will have to sharpen them yourself, but I know they will also work very well for you. Make sure you tune your bow properly and put the arrow in the chest and either of these heads will do the job.
