I have recently purchased a used 1993 Para-Flite Robo Z 225. I have been assured that the canopy has less than 500 jumps on it. Some have said that the canopy snivels horribly, and some have said the openning shock will give you wiplash. I have been assured their are no major defects in the canopy. Can anyone please give me some information on what this canopy is like ?
