Snivel, snivel, snivel (Spectre question)

[relyon 0]

I'll very much agree with the bulk of your reply, notably the part about pulling higher with known snively canopies, but ...

99% of the details of packing (i.e. where the nose is, how it's rolled, how the tail is prepared) disappear within a tenth of a second of the parachute hitting the air, so no packing trick in the world will change a 4 second snivel into a 3 second one.

I gotta disagree here. Depending on which tricks I use (rolling or not, which cells, which way, nose in or out of the tail, tail rolled or not, brakes stowed or unstowed, etc) I can get my Lightning to open anywhere from 1 ("it's full of stars...") to 4 seconds (ahhhhhhh), and anywhere in between. I can pack in an opening turn to either side as well, though I most often opt for straight on heading. It's all very possible and repeatable. I used the same tricks with my Triathlon 160 with similar controlled results.

Look at a dytter graph, they log everything and usually show about 500-700 feet is the time from initial slowdown to the end of the graph (open canopy)

Ok, your explanation about alti lag in freefall vs canopy makes perfect sense. I have Pro-Track graphs of all my jumps and just looked... on most of them it is very obvious where I started slowing down, and lo and behold, you're right, it was dead-on about 500 feet (!) for all of them. This does seem low for a Spectre but keep in mind as I pointed out earlier, when packing I do everything possible to try to make it open fast.

Another thing I noticed is I speed up 5-10mph before every pull, I can only assume that's from reaching for my hackey... my projected surface area decreases so my fall rate increases?

I agree that good packing techniques can reduce or eliminate the slammers on many canopies, but I do not believe that any careful placement of nose or tail will withstand 2 seconds of exposure to 120mph winds. A few moments in the wind and all that careful packing is gone, IMO.

The speed up is the change in pressure as you turn your head during yor wave off and just as you get swung straight up as the canopy is out of the bag.

Deep brakes can help, but this is more of an emergency manuever than a recommended normal procedure. Releasing brakes during an opening can lead to some very nasty problems/mals; I'd only do it under very specific conditions (like you're sniveling through 500 feet.)
***************************************

About Spectres and brake setting:
Usually Spectres actually open faster with a more shallow brake setting, and slower with a deep.

Keep in mind that this is canopy dependent and that there is usually no reason to alter the manufacturers settings.

I do just a plain ole propack on my Spectre 170 and it opens consistently soft, but not real snivelly. I did however, jump a Safire 2 169 awhile back, and that thing sniveled for what seemed like forever.

Now that you've had all this great advice may I point out. "first time using audible" First time on a Spectre, First time with a 1000 ft snivel. Thats BEER, BEER, BEER!

Helldog. . .I will have you know I paid LOTS AND LOTS AND LOTS of beer dues that night. . .

The party was a blast. . .

I always had to pop the brakes on my old Paraflite Astrobe (7-cell ~210) to get it to open.

It was kinda nice, like a trigger. I also had stay open toggles to help make it easy to grab them.

Probably 200 jumps doing this. Never a malfunction.

People are sick and tired of being told that ordinary and decent people are fed up in this country with being sick and tired. I’m certainly not, and I’m sick and tired of being told that I am

I jump a spectre 210 and experienced the same long snivel. All i can say is that after a few experimental jumps i found the best thing was to not tuck the nose in or roll the tail. In addition while opening i found that EVEN pressure to both of the rear risers speeds up the opening. This is taken purely from my limited personal experience and from advice given to me by more experienced jumpers but i hope it helps.
