I jump two 330 tandem canopies,they are excellent opening canopies, I have them on Vectors(Sigmas) so with the spilt toggles (I have a 2-steering 6-flare option)they are amazingly light to fly, and have a really powerful flare. They are also very fast,and are great in higher winds, even with small passengers. I have taken some rather heavy people on them and had no worries. I weight @175. Ive jumped the 364's as well and enjoyed them also. But for the ease of tandems the 330 is unreal. Not for the inexperienced tandem pilot though. Enjoy.
