You might keep this in mind - so far, no one I've helped finish a room or building has complained - quite the contrary. "Amped" in Austin finished his 20 x 24 "outbuilding" exactly as I recommended, after trying to deviate materials, etc, a few times - the end result was that he couldn't hear his drummer playing from outside the building 10 feet away. Next was acoustic treatment - again, he followed my suggestions and again, happy as a clam.
Nothing succeeds like success
On the other hand, me pappy used to tell me "never turn down an offer you haven't heard"... So let's just see where this leads, don't fret the small stuff, and maybe we can ALL learn a bit. That's my diabolical plan, stan...
As for your own projects, you know you can stop studying this crap any time it gets to be more than you want to deal with, and I'll still do my best to keep you from any mistakes as long as you talk it out BEFORE you build; so again, I wouldn't sweat the small stuff Rick, I've got your back... Steve
