Multi Can't Post

Hey, how many of you are still using the multi? Does CR advise using it on their canopies? Is center cell strip as bad as we thought it was, or is the problem being dealt with by proper PC selection?

Any pro's and con's to the multi?

Here's a short version. These are my opinions only.

In reply to:

I use it on my FOX (um, when I have a PC on it). I have around 400 jumps with the multi. I haven't really been able to tell a difference, but I haven't worked too hard at it (I've never jumped the same canopy consecutively with and without the multi, to compare, for example).

In reply to:

The multi has to be manufactured into the canopy (since you essentially have to create four bridle attachment points). CR does not offer a multi on their gear (although I heard a rumor a while back that they were working on a blow-off multiple attachment system--you might want to ask Adam directly about that).

In reply to:

That's open to a lot of discussion. The consensus appears to be that center cell strip is a problem on ZP topskin canopies. BR addresses this with the multi, CR addresses it by not putting ZP around the attachment point (i.e. composite topskin).

I personally think that center cell strip is still a problem, but I am not convinced that the multi is the best solution. Vertigo uses a system called a top gate, which I think is probably the first step in the direction of a better solution.

In reply to:

Pros: Reduces center cell strip, makes deployment a little neater (somewhat arguably).
Cons: Some (minimal) chance for a weird entanglement.

I'm not personally convinced that it's worth the extra $150.

I do know that some scandinavian jumpers have removed the multis from their canopies entirely, because they felt that it was actually hurting their opening headings. I haven't felt that way on my multi jumps, but they obviously felt strongly enough to remove them.

AS for the multi, I tend to agree with those who have removed it. I made a number of 1-3 second delays with the multi and felt I was having way too many off headings, to include several 180's. I took the multi off and definately feel there was no degredation in heading and probably an improvement. There are way too many factors affecting heading performance to narrow this down, but my multi is still off and likely to stay that way.

I have used the multi on over 700 jumps and it has never been the reason for a critical off heading opening although there ahve been many other resons I've hit the wall three times and had line twists at least 10 times on a BASE jump...Laugh
