what effect does very low wingloading have on openings?
Do you have a theory or even experience of the effect on openings on canopies with 0.5 lbs/sqft wingloading, compared to canopies with 0.7 wingloading?

Re: [wilcox] what effect does very low wingloading have on openings?
I think it relates more to the fill volume of the canopy and the weight differences between the canopies. For example, a large heavy canopy may finish line stretch in more time for a given size pilot chute compared to a smaller canopy. A larger canopy will generally inflate slower than a smaller canopy, simply from the much greater fill volume of requisite air flow to complete the inflation process for a larger canopy.

My comments refer only to slider down opening characteristics. This is based on my personal experience jumping wingloadings down to around .55, and observing other jumps made on canopies loaded as low as .49. As you reduce wingloading, the openings become somewhat less consistent. You can expect to see some jellyfishing, slower openings, and weird pressurization issues. End cell closure can become very common.
Two things to keep in mind:
1) This effect is much more noticeable with larger canopies.
2) This happens much less on canopies with bottom skin inlets.
So, you can get cleaner openings from very lightly loaded canopies in two ways: jump vented canopies, and be a very small person.

"bottom skin inlets..." whats wrong with calling them Vents?
Politicaly correct, non-brand offensive?
Did you get those risers back?

"Inlets" is more accurate.
Inlets = vent or valve
Valve = one way airflow (in only, like PAC valve, MDV, or vtec with covers)
Vent = 2 way airflow (in and out, like vtec with no covers)
In this case my comments apply to vented or valved canopies, hence I used "inlets" to cover both possibilities.

A very astute observation.
