Hi Gerry,
As I now have WFP I rarely need to wear my belt with its various pouches, slots, hoops and god knows what else hanging off it!
I have a large variety of squeeggees and still use them when required.
I carry them all, and always have done in my bucket.
4 of them are clipped into a handle ready for use, the others rest in the bottom of the bucket.
Generally I would carry on my person those which I knew/know I was going to need.
My BOAB is the blue one (have forgotten which make! It isn't an Unger one) can be used left or right handed, is quick release and can hold 3 squeegees + applicator.
Have never found I needed to carry more than that actually on me.
Ian
