TAC-1 chute vs. round chutes?

[jraice]

I want to use a descent rate calulater to calc the speed my rocket will fall on a TAC-1 chute and a 30" drogue. The TAC-1 is shaped way different then a round chute and I have heard they are more efficient. What size round chute would have the same amount of drag as a TAC-1 size 72 chute?

I suggest you contact Ed at Giant Leap and ask him. He's the sole marketer of them, He probably ought to post that info on the site.
