Kinda late to reply here, but I tried them out a while ago. Ended up going with the Slick Trick Standards, I just think the Standards punch through bone a little better. Either the Viper Tricks or the Standards would be a great choice just depends on if you prefer CoC or whatever the design of the Standard is called. I have gone through two deer (at different times) with the Standards, where I punched through shoulder blades and still had pass-throughs. One at 25 yds. and one at 55 yds., both with a 430gr arrow going 265fps, so not a powerhouse setup by any means.
One thing to mention about why I chose Slick Trick I like the four-blade design instead of the popular three-blade design of Montec and others. Saw a video about it a while ago with four blades, you are only splitting bone in two total directions, whereas with a three-blade broadhead, you're splitting bone in three directions. Maybe the extra energy to split bone three ways vs. two is irrelevant, I've had some pass-throughs with Montecs going through shoulder blades, but I have had nothing but pass-throughs with Slick Tricks so I keep using em.
