    The basic one is not 20 bucks. When you try to order it the amount is higher than that. It's a typo on their site. I actually notified them about this in July of this year but I guess they didn't bother changing it.
  2. Reserves canopies tend to not have diving line twists by design. It's easy to know why as you absolutely don't want them when you deploy your reserve. If you think about it the other way you can sort of deduct why reserves don't have them. High performance canopies (that tend to have more diving line twists) for example have an extra 2 cells (so 9 instead of 7), a planform that's more elliptical especially at the sides (for those quick turns), a thinner airfoil (less drag = more speed), a higher aspect ratio, crossbracing. If you don't have all of these things by design you're basically left with a canopy that just wants to fly slow and straight and there you have it.
  3. Well.. You hit the nail on the head there! In my country you're allowed to exit 'on your own' after you hit A license but nowhere in the theory you need to learn is anything about exit order, exit time, ground speed of aircraft etc.etc. Glad you become somewhat wiser in this thread, definitely a good question!
  4. I have them, and can definitely let you know sometime this season as I intend to try it out.
  5. Look. If you have to track up / down jumprun to get away from your group members in order to avoid a possible canopy colission. You must right? If during break-off, two people track away perpendicular to jumprun, are the other jumpers supposed to simply open and fly into eachother because they're not supposed to track up/down jumprun? It doesn't make sense, does it? In a 4 way at least 2 jumpers would be tracking up/down jumprun to at least some extent... It's impossible not to. Naturally, You're eating up some of the margin between the other group, but that margin should be accounted for by the time between exits! That is the reason you leave more time between and after groups, than after solo's. Who would cover more ground in 5 seconds? Your plane or you whilst tracking? Hope you understand the logic behind it. To give you an example: I'm sure you understand that if you start your break-off at 6000 feet, it would be very smart to inform the next group of this plan and ask for more exit separation. Same way, if you notice you are tracking up/down jumprun and you can visually see you're far enough from your group members. You can and should open your parachute right?
  6. Why are you supposed to track away from the center of your group? A: To avoid canopy collissions with members of your group. How do you account for separation between groups / exits? A: To allow enough time between exits. Bigger groups = bigger chance of tracking away on jumprun at the end of the jump. So you need more time between (or after) group exits than solo exits. If you're not tracking away because you're on jumprun you risk a canopy collision with someone for your group. I'm sure you understand that's not the right solution.
