i agree that it sounds alittle overkill, but i am not totally sold on sips...i am not a fan of osb, and theyre expensive to boot. seeing that i am not hampered by time constraints, i dont mind building the "skin" out of 2x material.

what i would like to know is if you guys think this is workable, and if i am re-inventing the wheel so to speak...

on another note, the knowledge that i have gotten from this web site has been invaluable to my understanding of tf'ing..many many thanks to all
