I have 31 ft & 60 ft x-tel, the 31 ft is great ,it will reach up to 4 floors and not to heavy with short sections so will fit into smaller vans,
The 60 ft pole is the best pole ive used so far as again short sections (6ft) so will fit in most vans this also makes it easier when raising or lowering the pole especially in confined spaces, it weighs 6.5 kgs which is light compared to what im used to i would say this is the ideal pole for residential or small commercial job as its quick and easy to put up
i havent tried a gardiner pole yet but i dont have a big enough job to warrant buying one
this is my opinion and the poles i have used previously are ionics which are twice the weight & brodex which were simular weight but brittle and rigid
hope this helps
