When hunting for my crystals I started wondering if there was an efficiency/stability advantages between the different case sizes. I have found the same frequency in 3 different packages. According to the seller they are all the same type (slice, shape,freq) just different outer cans.
Can anyone here shed any light on the differences?

well if you have some different crystals in hand you can experiment, but I would not go to the trouble of ordering them.
last I looked KC9ON had some crystals at decent prices
