Hi,
There is also the hybrid aerodynamic container aimed for more experienced jumpers? both containers Zak and Hybrid made by Adrenalin are available with L-bar or 3ring cutaway which is a free option with little added weight.
Personally, years ago i used to have a 3 ring cutaway. Today i choose to have direct risers for its advantages and try to not put myself in a situation where I would need to cut away, if I did have to, I wouldn't hesitate cutting directly the risers as it is an easy operation putting new ones on.
