Rotary "Summer" Unit GB interest

[xIceHoundx]

Richard could you tell us reasoning for the stop in production of the HFS-6 system and what the exact differences are between the HFS-3 and HFS-6 especially in how it pertains to rotary and use with the summer? I personally am one of those overkill kinda guys and would rather spend money on the product with the most options and tuneability so that later down the road when I go higher I dont find myself having to replace as much.
