Which square?
Skyfrog-
For those of us with a similar background, care to share which square you put in your container? Their website doesn't list compatible canopies other than the conicals, or pack volumes. What about cost premium on the square option?
I'm thinking a Stiletto 120 with dive loops on the front risers? Ok, just kidding on that one (and I probably dated myself by making that comment).
Part of the decision is obviously opening speed from sub terminal...I imagine a round is better for this? Though, the BASE guys are using squares from insanely low altitudes these days.

No need for dive loops when you have a nice big 4-point stitch pattern at the end of the Type-7 riser
I know the question wasn't directed towards me, but after videoing PD drop tests, that's my choice. One of the tests was for the 99R with 310 lbs. at 200 knots, some other tests (bigger canopies & more weight) were done at 240 knots. At those speeds packing tabs were whipping around so fast they were burning holes in the top skin  so we cut them off

Emergency Parachutes
www.parachuteshop.com has specific emergency chute recommendations for various aircraft, including RVs. They carry all major brands and occasionally have used pilot and skydiving gear. They are a full service shop (repair, rigging, etc).
As an added bonus you may spot Doug Reeves' alter ego...

don't unbuckle first?
In this thread--I was surprised to read that you open canopy prior to releasing your seat belts.
In the 7a slider, I can't move much and I don't have much backwards arm strength.
I would envision myself having to pivot on my knees to push the canopy open.
(one day I was preflighting the RV and a instructor watching a solo student walked over; and asked me if, like his old Grumman, could I fly with the canopy open. I explained -- nope, these canopies need to be closed and won't open anyway.
I take off and get over the lake and the plane noise is getting louder and louder. My canopy was an inch or two open. I closed and latched it easily. And then berated myself the rest of the flight.)

I have the PD Reserve-253, stuffed into a MiniSoftie container. The chute is the right size for my weight, however I'm not sure how well the container will work in an RV9.
Does anyone know the preferred container for RV?

Through the Canopy?
I've noticed all the talk of the potential difficulty/impossibility of getting an RV-7 sliding canopy open in flight in order to ops check egress. What about not trying and going through the canopy? A crash knife or compact emergency hammer should do the trick. It's not like you'd expect the thing to be reusable anyway. Would that be practical?

Not really - it would take a while to bang around and you don't have good angles. If the _very_ unlikely happened and you needed to bail from a slider RV, I think you are better pulling the handle and sliding it back. If the canopy don't open just pull the pins.
