I have the Black Ops on the front and the Acme stinger on the tail. Maybe along with my slats, adding those shocks were the single best up-grade I've made to my SQ. They're clean in flight and dampen extremely well. It's such a huge benefit to literally never bounce when landing on a rough strip or bank. And, I love that they don't seem to cause the airplane to "dart" if during a crosswind take off or, a rough roll out, they become unevenly loaded. I've heard other shocks can do that? Obviously, good technique will get you through with no shocks better that shocks will get you through with **** technique but, man..... my Acme shocks sure allow for some margin when the landings are on really rough terrain and there's no going around. I love them. I think people discuss performance a lot but, safety is a huge benefit in my humble opinion. Also, as pointed out above.... I like that if you ever had a blown seal, the spring will still get you outta there and home. I've heard of another pilot who had a different shock, landed (not even particularly hard) on a gravel island and one of his shocks failed. Lop sided and flat, he needed a new shock to be able to get his bird off that island. Sounded stressful as the river had a daily rise with melt water during the afternoon.....
