Re: Fiberskyn on 18" BD
I play a Yammie Tour Custom Maple Bop with an 18" kick.
I put the clear thin EMAD on the batter side, (stock reso-so far) and it works great. The fact that I can change the response on the fly among three options is useful to quickly dial in to different requirements.
I wouldn't be too hasty to get the thicker or coated variants, but that's me.
