I,ve used Tucker for 4 1/2 years & still think they are the best for heavy duty or employee use. I,ve converted all poles to pennel clamps & have them on 3 vans, we do use other poles aswell but quality of use & brush is the best.
Alot depends on money & brush, but, the cheap g/fibre poles burn out fast. on everyday use, some have converted to salmon or gazh20 brush,s i,ve got one to try but not used it yet.
You just need the work to warrant the investment.
