Try ectreme 18, soo much better ?Does it make that much of a difference though? I've got an SLX22 and I remember looking at the weights of the Xtreme poles. I'm not going to look at it now but I remember working out that by removing a section of the SLX22 it would be close to the weight of an extreme pole. So as an experiment I removed a section for a day [effectively using it as an SLX18] working houses that wouldn't need the extra length. Although it was lighter, it was no where near a difference as I thought it would be, I'd say the difference was 'slight difference', it didn't feel like it would make a big difference.
I have both slx and ext, I see big difference when I need to use slx, ok if straight up easy windows, but anything more difficult its a day and night deifference.
