Helium Pin Cover Flap Issue
I've got a He paired with a Troll DW and been using it mostly for slider down jumping. Everything works beautifully and no complaints there.
I took to to terminal (WS) for the first time and my pin cover flap blew open almost immediately. It was all over the place for the duration of the flight and looked pretty spooky on film.
My closing loops were a little long so I've shortened them. Problem is, it's a really tight fit. It should be no problem for terminal jumps, but I made the closing loops out of spectra just to be a little faster on lower stuff.
All that said, the cover flap still seems pretty loose. I'll have to take it to terminal again to be sure, but I suspect that it will open again.
Anyone else have a similar experience? Were shorter closing loops enough to fix this or was a larger fix required?
Apex offers that option/mod on their summit/tl/tls.
I have the mod on my summit and like it, however it is one more thing to change when going SU/SD and vice versa (for those that prefer the KISS methodology).
It may be a bit of over-design, however I have had a few rear facing videos where the pin protector flap has come open during WS flights on dives and it is quite unsettling, considering you have no idea that it is happening while you are flying. Even after adjusting pack job and closing loop length it was still an issue, so the stiffener worked great for me. It's gives me that nice warm and fuzzy feeling on exit. That being said, I have friends that also have summits and they have had no issues with the pin flap being pulled open.

If you open the flap when you jump S/D all is fixed!
If you only stiffen the top edge of the flap it shouldn't interfere with slider down jumps at all. Leave the bottom edge alone and your pins will pull long before your bridle gets near the newly stiffened section.
The following solution was proposed to me by a very reliable source. I think it makes sense and I don't see any issues with it. That said, I'll put it out to the field and see if someone more knowledgable than myself has a negative view of this fix.
I used a small plastic piece which is designed to bind report covers to stiffen only to top edge of the cover flap. Here's a link to the actual product:
I cut down the "sliding bar" to the length of the pin cover flap along the top and melted the edges down to make sure they weren't sharp. I'm sure many of you used these types of report covers back in junior high so you know what these things look like.
See the attached images. I've been told this solution has been put into place with Summits with good results.
I don't see any issue. The flap still opens without difficulty, but is stiffer (only at the top edge) which should help prevent unintended openings. The plastic piece slides on and off easily and can be removed for subterminal jumps. I open the flap up for S/D anyway.
Anyway, take a look at the photos and let me know your thoughts. An open pin cover flap on WS jumps is not an option. The bridle flaps everywhere and I don't want a premature opening.

I played with it some more and can't get it to cause any hang-ups. The worst thing I could think of was to jam the whole plastic piece under the tuck flap. It can still be opened from the top, and the bridle always pulls from the bottom anyway.
Jumping it tomorrow and I'll post footage of the opening.
I never contacted the manufacturer as my "plastic book report spine" worked well enough as a bandaid for what I needed. After my trip I just sold the rig and bought something more appropriate for the type of jumping I was doing.
My new official position is to recommend a TL or Summit though.
