This winter (and spring and summer and fall and...)I'll be finishing my basement. My music / HT room will be 8.5' x 13.5' x 22' and I would like to use metal studs. Are there any negatives to this? I'll will be double sheeting the walls with 1/2" or 5/8" gypsum wall board. Studs will be set 16" on-center with cross bracing and insulation between studs.Is this going to be bad (too much wall flex.) The reason for using metal studs in the first place is cost - pure and simple. Should I just cough up the extra cash for wood studs or am I going to be OK?.....Colin
