I psycho pack, push the nose right back, pull the slider forward and roll the crap out of the tail! I tried a different tail treatment a few weeks ago and it told me it didn't like it! I have a 135 loaded about 1.4. btw, I am 'the packer' and I treat my gear the same as everybody elses....DC
I have a Sabre 210 that I got when it had about 250 jumps on it and I have put about 50 on it since then. I am loading it at about 1.3:1 (yeah, I'm an anvil).
It used to spank the bejesus out of me on about every 5th jump. I had a rigger and two packers try to work their packing magic on it with no luck. There was always that jump right around the corner that would leave me bruised and walking funny for a couple of days.
It came with an oversized slider that didn't seem to work. I finally cured it by having my rigger put a small pocket on the slider and I now psycho-pack it. Since then, it opens like a dream. With the slider pocket I can pretty much leave the nose hanging and barely roll the tail and it still gives a nice soft opening.
Well... except for the time that I accidentally packed it with the slider still stowed, but that's another painful story.
