Ditto.... I did the same when I ordered the 125gr Slick Tricks. I shot Thunderheads for years and ended up tossing them out.

Right now I shoot Magnus Stinger 4-blade 125 grain and shootSlick Tricks for when it is windy. You will be amazed at how well they fly! I mean, you could shoot them in a bad, swirling, 35mph wind, and they will still hit dead on!
