Re: [mrmanta] modified dragon 220
The Dragon was an early Vertigo canopy (before the Dagger).
It had a reputation for not-so-nice pressurization when compared with the Mojo and FOX (the other standard canopies of the day). It's definitely not as nice as the Dagger (which superceded it) or pretty much any other modern BASE canopy.
There were some floating around that had been modified with bottom skin inlets. I'm not sure if that is what is meant by "base modified" but it's possible. Do you have a link to the advertisement?
