Does the P-18 have the button on top? If it is was it easy to get used to having the button in that spot? I bought a Kick to use on my Indulgence wood mod but it didn't fit right so I sold it in the classies in about two minutes. It worked really good though but with the Indulgence it was hard to get the proper shim and to remove it to adjust it. I might get another later though because they are pretty cool if you have the right pv with them.
