Ok man,
You may think you are capable of controlling this canopy, and you say that you had a serius linetwist on the canopy, Was the canopy spinning or whas it just linetwists?
When you have 60 jumps it might seem like a serius linetwists if you have a bunch of them, but as long as the canopy is flying straight you have no idea of what a serius linetwists are. If you check out Nitros website it says that this canopy is for Advanced and Expert skydivers, and lets face it, you are neither after all of your 60 jumps.
Take a step back and think before you do something you might forget.
Take the advice from all these people that this canopy is not for you yet... Skydivers are a bunch of insensitive jerks...
And that's why I don't skydive anymore!
