As for your Question #2 ...
if you know how to shuffle chips, any chip should be easy to shuffle. I will say though that I've noticed that Chipcos seem to be very well centered when compared to other chips ... what I mean is, if you riffle a stack of Chipcos and then NOT push them together to form 1 stack (just leave them all in mid shuffle where all the chips are half mixed into each other) and then apply some pressure to the top chip with your finger, they don't wobble or fall ... doing this with a clay chip for example, will cause the "half shuffled stack" to wobble and fall over ... if I only had pictures to show exactly what I mean.
