First of all great choice of brush you won't regret it with a gardiners, that brush is a great starter brush and all rounder, I used it everyday untill I tried an extreme brush and now use that as my regular cleans due to being much lighter but I still use the superlite for first cleans as it does give a deeper clean for those really dirty first time jobs.
Maybe look at swivel heads too they as a game changer for me being able to work at an angle and know the brush is flat to the glass!
