I had Hornet 170 for my first canopy. never had a slammer with it but the line kit was out of trim. I tried to get a new line set from PISA and found out they had just been bought by aerodyne. called aerodyne for a new line set and after sending my hornet back to them they called me back to offer me 40% off or so on a new canopy if they can keep the hornet. I think for a while Aerodyne was producing in SA but ownership of Aerodyne has tragically changed since then and I think the SA factory is now doing military stuff. please correct me if I am wrong!. Aerodyne still have a small factory in South Africa, working primarily on R & D projects. PISA are producing only military gear, both static line and free-fall, but unfortunately no longer produce the Hornet. The Hornet is technically 'semi-eliptical' while the 'Heatwave' was their fully eliptical canopy. Hope this helps!
