Hi mates, First of all, excuse for my English, I am not from English-spoken country. I want to compare between these poles. Do somebody use them? I need to work up to 80 ft. I need it for an employer team, that cleans industrial buildings. Is X-treme works good above 70 ft. I will need to use a lot of extensions. Are Extension sections of Xtreme compatible with Ultimate? (The cost of Ultimate is high, I think to save money and buy Ultimate pole and less expensive extension section of Xtreme. Thanks for answers.
