RE: If you had to choose...
While I think they are all good choices. Grading them on the4properties I look for in a Broadhead Flight, toughness, quality, and ability to inflict damage. I think the Slick Trick is the clear winner. If you needed more penetration then the Hellrazor might be my choice but not with any NA game. Muzzy's are a good broadhead at a great price point, but when it comes to flight and toughness the ST will win out for just a few $ more.
