from cleansmart ....
I would get the two jet ... its a lightweight good allrounder and the total flow is 3 .. works well with your pump and inline heater .
(The total flow of the 4 jet would be 6 )
Also i would get the glide they sell for the two jet ... its a high quality green glide , and its on sale now .
Also get the booster your considering , it would help when using the glided wand , there will be less back effort though.
