Before you spend any money or waste anymore time, tune your bow for broadheads as stated earlier using the easton broadhead tuning guide. You just move the rest minutely. The broadheads will adjust more than the field points, and when they start hitting the same spot, adjust your sites. I had the exact same issue. You should not have to adjust your sites every time you want to hunt. Each different type of broadhead will shoot a little different and just because a head shoots just like a field point without any adjustment does not mean it is better than one that does not, it just means you got lucky and the bow is tuned for that particular broadhead. All the broadhead needs to do is be consistent with itself, then it is up to you to get it hitting the same spot as feild points. Broadhead manufactures should give out tuning instructions, they would keep a lot of customers that way.
