I just started flying your 550 Cruiser and I love it. I lost about 20 FPM climb rate from my Thunder Bolt 340 but way better climb than a Rectangle chute. But I gained a whole bunch of confidence in take off and landing. I felt unsafe with the Thunder Bolt. I have never seen a chute that comes up that fast and perfect. I am flying 34 MPH with this chute and the Thunder Bolt flew at 39 MPH. I like the slower speed on take off and landing on rough runways. Thank You taking the time to make a better chute.
