hello from Whidbey Island WA ....my wife & I are in our final process of selection & elimination for our hot tub purchase .....we are looking 5 to 6 person, but there must be 1 lounge position only, and that position has to hit back, backs of calfs and bottoms of feet .....for Sundance, we are looking at Montclair (780 series) .......for Hot Springs, we are looking at Pace (Hot Spot series) .....we understand no UV sterilization on Hot Springs, only Sundance .....but if anyone can pass along other pros & cons of each company's tub's filtration, as well as any compares between these 2 tubs directly we may not be aware of, we'd highly appreciate ....we also understand the Pace can be 120 direct plugged in, but we'd convert to 240 for the extra power that would provide to the jetting system ....thank you kindly for the help & education !
