How much louder are soft tops?

[bullsnake]

I'm assuming the Alpha's have a pretty good heating and cooling system as well? I'm in Iowa and we currently have 6" of snow on the ground with an expected high today of 12 degrees. The heater in the 'ol 96 will run you out on high! I'm assuming the insulated soft top stays nice and toasty too in the winter?
Haven't really had an H1 through the summer-can the AC keep you from getting completely pitted out if you were heading out to an event?

Thanks!!
