I am not looking to start an argument, I just want to understand what your intentions are when you are doing magic and your doubles?
Are you doing them for show or are you doing them to fool?
If you are doing them as part of a magic routine, then the more natural or classical (or what you think is "easy" and "unoriginal") double lifts are disarming and can be geared as a natural moment in the effect. It is my belief, and many other pros, that double lifts are overexposed because of their poor handling, that only novices believe that doubles are easy...when usually they don't understand timing, don't perform good get readys, and they flash all the time.
The DL is NOT as easy to perform and be deceptive as you might think, as the thickness and handling is a tell...don't believe me - get a friend and do doubles and singles for him...then put your money where you mouth is - ask him to tell you which is which - a dollar if he is right, a dollar for you if he is wrong - I PROMISE you will be broke...especially, if you are handling cards in such a flamboyant manner.
If it is for show - and you are into cardistry - then realize that you are completely exposing a DL - as I challenge you to handle a single card in the same manner....even if you could, why would it matter? What are you showing when you do it? Skill.
The concept of strong magic is to hide skill, not display it. If you want to display skill - do flourishes, but stop exposing classic sleights by your poor handling.
Concluding thoughts for you - if you want to be ORIGINAL, try doing the "classic" moves really well - so well that it can withstand scrutiny - because magicians like that are far and few between - where guys like you that want the credit and immidiate feedback for the effort they put in...are a dime a dozen...this site is LITTERED with them.
Like Lisa Simpson said to Bart when he got an ear ring, I will say the same to you doing fancy flourishes and over handled sleights.......
How rebellious! In a conformist sort of way.
