Additionally, if you cut off a small piece or two of Arizer Extreme Q whip and put it over the end of the mouthpiece on your omnivap/etc, you can then use the Silicone mouthpiece cover that comes with the Grasshopper as your SonG adapter to sit over the piece of whip Fits like a glove!
Of course, if you don't have a grassphopper Silicone cover handy, definitely get the Delta 3d Studios adapter as it obviously requires less assembly, also @Ratchett is good people
Noice, I have a couple of hopper silicone mouthpieces here, good to know. Thanks for the answers guys, very informative. If I ever happen to order an omnivap in a near future, I'm sure I'll order some accessories from @Ratchett
