Best kneeboard for helicopter pilots  

Hey folks,

I'm curious to see the consensus among our community of rotorheads which conventional (non-ipad or device centric) kneeboard is the best. I have started to more compact kneeboards available in recent years.

I use an older ASA IFR kneeboard which at times is cumbersome yet it is useful for stowing approach plates as they tuck away into one of the side folds versus having open pages flapping around on the side.

Thanks for your feedback.
