I won' t comment on your dealer, but he is not being very helpful to say the least! Go to my site, www.broadheadtests.com click on the tuning link and read it over. Not every broadhead will shoot like field points with every setup, but after reading that section over you will better understand why. Bottom line you need at least a 4" helical fletch with a well tuned bow with matched equipment to get good consistant fixed blade broadhead groups. I use a moderate helical and am able to get excellent accuracy from just about every fixed blade head I shoot, and belive me I am not exspert, I just spend enough time tuning and playing with my equipment to know what works for me. If you have any questions after reading over the info, email me and I would be glad to help out.
