I am toying with the idea of eventually getting an Extreme 35 or, less likely a 40 next tax year. For a handful of our jobs that are a real stretch and a heavy struggle with the SLX 30. Serious consideration and head scratching required as the extreme 35 is around £1000 give or take.Cheers ? yeh I reckon a 39 would be much heavier. Hopefully the panels would take most of the weight? But true, sometimes even with the 22 its a struggle, usually when at angles for awkward ones, or over connys. I'd prob only use a 39 for panel jobs and 3 story top floors. This 50 panel job would pay a big chunk for it after the first time, and I think it would be yearly but I see what you mean if it got hardly used.
