Okay, many thanks to all those who helped me identify a 410 as my best solution. Now, since MF has dropped the price significantly on the Aggie S-series cabs, it's down to sound between these two. Opinions? I'll be powering either with a SVT-II (4 ohms) and playing rock (some surfy rock and fuzzy garage rock, mainly) The only other major difference is that the Aggie weighs about 17 lbs more than the Avatar. Thanks in advance!
