Jet Internal, Pentair, Cyclone Jet, 5" face diameter, Swirl, Textured, Gray

Okay, so there are a few jet styles available that fit these older tubs. I sampled a few of them and here are my thoughts... 1) Swirl - Swirl is my favorite. The single jet can be adjusted to swirl in a very narrow or a very wide pattern - just grab it and point it as far to one side as you like, then it will resume rotating. It provides a powerful stream with a very nice massaging effect. 2) Twin Roto - Second favorite. Not as powerful as swirl. Spins quickly and creates more of a pulsating feel. 3) 7 Hole Roto - Somewhat disappointing. I think this one just requires more water flow than my configuration has to offer, and frankly I wonder if the narrow inlet would ever allow enough flow to make this jet sing. 4) Directional - This is the simple boring one. Descent power, simple point and shoot operation. Note, I couldn't care less about various colors and textures and scalloping, so that is not considered in my review.
