Well, I got the bug. The "I need something new" bug. Fortunately I hadn't given into this yet until today. Last night I was shootin the Stinger 4-blade heads that I liked so much, when I noticed that a couple of the heads started drifting left while the rest were perfect. I inspected everything to find out that the main blade had been bent very very slightly on both. These were brand new out of the package heads that I shot maybe 5 times into a Morrel Yellow Jacket target. So i tossed those two and sold the rest of my stingers today. Of course that was only half of it... I really really wanted to try the Slick Tricks with all the good things I've been hearing about them. So.... I'm done buying stuff for a while, I'll let ya know my thoughts on the ST's. Thanks for listening to be ramble.
