Anyone ever ran one of these chargers? Looking at trading my fleece 68 for this one. On the website it doesn't specify if it's a 4094 but looking at the pictures it looks like a 4094. Are these comparable to a 4094? I'm sure someone will say switch to a fixed vane charger, I'm going to take a pass on a solid vane because I'm remaining vgt for work stock class here. Thanks in advance !
