Has anyone tried the 135?
Nice, what's the veg footprint on the 65s?
I think you might want a couple more of the 135s in a 4x4, the 550 uses 4 qbs and 480+w for that footprint. I use 2 320xl v2 Rspecs in my 4x4 and they are amazing. They have 3qbs each and run at 320w. They weren't cheap (~ $860), but they have already paid for themselves 3-4x in the ~3 1/2 months I've had them. Well worth the investment, especially if you have heat issues and hate electric bills.
