Jack from PA - "Jack Strap"

[manship 0]

There was a man from PA in Twin falls around Memorial Day. His name was Jack and he was using a "Jack Strap" on his rear lines -- like 1/4 of a slider. I would like to ask him some questions, as I am not getting good results trying one out.

Could anyone tell me (or PM me) his contact information, or ask him to contact me.

Thanks,

I didn't invent skydiving, but I jumped with the guys who did.

Yo Tom,

I jumped a Jack-Strap while I was out there in May. It opened the same as a slider down. I haven't talked to Jack since last year, but I'll check to see if the number I have is current. How many have you done wiht thge strap and how have they worked?

Cya,
