What are the XTel poles like that come with the pure freedom trolley package? i was thinking of upgrading the pole on the 25 litre package to the 20ft XTEL Hybrid if it is better than the standard glass fibre XTEL. Any better poles? was thinking of just getting the trolley on its own and then buying a pole/brush else where if the XTel are not up to much. Will be new to WFP, how many different brushes will i need to start out?
