What you are describing does sound kinda strange. I have to agree with 5 shot about the idea that it is very unlikely to be the Slick Tricks. In my experience, the Slick Tricks are much more likely to give field point flight and accuracy than most other heads I've tried such as Muzzy. If there is a problem with the tune of your bow, then you will probably notice poor flight with broadheads, and most likely different impact point compared to field points. If your broadhead tipped arrows hit in the same general place as field tips, but group and or fly much worse, then there may be an arrow-related problem. I'd try numbering the arrows, to see if individual arrows are consistently shooting off. Try putting the broadheads on the arrow, then spinning the arrows on the tip of the broadhead to check for any wobble. If these arrows are a few years old, they may have spine issues leading to poor accuracy with broadheads. Why do I mention this? A few years ago, I bought a used bow that had several CE Terminator Select arrows with it. This is actually a better grade of arrow than you mentioned (.003 straightness compared to .006). I got 9 arrows with the bow. 5 of them would shoot well with broadheads, and 4 would not. At ranges beyond 30 yards, they were off enough to be scary. They shot decent with field points, but not with broadheads. Any misalignment or problem with the arrows will give you fits trying to shoot open blade broadheads, even Slick Tricks. The fletching you are using may not be controlling the arrow flight well enough also. Helical fletched Blazers should give you good control, as long as the fletching is not contacting your rest, riser, or cables. Hope this helps.
