i find with this change,(i dont know if this is exposure,sorry if it is) if you curl ur fingers in a natural position, and just as you reach the deck straighten them out.then there is no need for a forward pushing motion which looks a bit suspicious.
Also if you push light enough with ur pinky(as in a TP) then the fingers holding the deck should keep the other cards secure.
As for the "less pint dependant" method, i normally find if my hands are a bit dry then a "small cough into a cupped fist", will give them more than enough "warm moisture" for the task at hand.not excactly hygenic,but its all about the magic at the end of the day
