Truth to it all is that the ability of a kite to perform comes down to the pilot. It doesn't matter how good the kite is made, it doesn't matter what material is used, doesn't even matter how the stitching is done. If a pilot is a good enough pilot, they can make "just about" any kite perform like a high end $300.00 kite. The E3 can jacobs ladder just as easy as the Exile. As far as it's ability to perform (certain) tricks, the E3 is just as good a kite as some of the high end boutique kites. Just because it is mass produced doesn't mean that it can't perform. With a good enough pilot, the E3 is capable of doing some pretty amazing things that would impress even the best of the best.
I think the operative word in this whole statement is "IF
a pilot is a good enough pilot..."
What if he or she isn't???
I have no doubt what so ever you could change the sail graphics on the E3 and put a Benson label on it and they'd think it was the most amazing kite ever.
Have you ever flown a Benson Kite?
The E3 is more of an all around design that doesn't have any radical tendencies. If they had designed it to have radical pitch ability, than I doubt the target audience for the E3 would be very happy.
The kite wasn't designed for the .000001% of kite flyers who want a radical kite.
I think that more than 1 in 100,000 people who buy dual line kites want to do radical tricks!
With that said, the E3 will take you as far as you want to reasonably go. Trust me, it will do every trick in the book. Going out and buying a 400 dollar custom boutique kite isn't going to make you a better flier.
I, personally, am NOT a reasonably person about kite flying. I want to become very good at it. So I buy the best tools that I can find to achieve that goal. A boutique kite will not guaranty that you will become a better kite flyer but it will speed up the process towards that goal.
A very personal opinion..., Please do not compare a Benson DS to a E3.
