I have a Javelin J2 and the biggest canopy it would take is a 170 but 7 cell because of the pack volume. Try getting a 7 cell canopy something like a triathlon, storm, spectre, ect.
I am new to this sport and I'm trying to get a used rig. My question is, can an RSL be installed on containers that doesn't have it? Also can a container be turned into freefly friendly? All answers are welcome, thanks in advance!
