Looking to replace my wisperflow 2 hp with a variable speed magnetic induction pump. Power bills are killing me... Looking at 3 options currently; Intelliflo vs, intelliflo vf, AO Smith V-green. Does anyone have experience with these? I have a compool lx easy touch controller and am not sure if controls are compatible. Running Slide water and water falls and don't want to make this too complicated to run them. I think the vs is fine with it but not sure about vf. and really don't know about AO Smith motor. With AO Smith need to use wet end from wisperflow but doesn't look like a big deal. This could save up to 500$ but not sure if unit is any good. Any comment appreciated....
