Weird JFK Pilot Chute

[p5yc071c]

I just wanted to post these pictures so that we can learn from them. I jumped at YO and pulled at about 6 seconds with a 36" PC. Manufacturer suggests 38" PC w/ 4-7 seconds and 32" for terminal jumps. On heading opening, but immediately after releasing the brakes I started an uncommanded left turn. This turn continued even with full right toggle input. After wrapping my toggle around my hand I was able to turn back to the right...but somewhere on deployment my PC had flown in front of my parachute and become snagged on my left Stabilizer. If anyone has any input into possible causes, I'm all ears. About the best I can figure so far is a handle that is too heavy...still seems like it would be a bit much to assume it was the size of the PC. I took this picture immediately after landing.
