a extreme 22 is a hell of a lot liter in the hand compared to a slx 22, i wouldent bother with the xline poles ive got the nano 25 and its top heavy and the clamps are poor, gardner poles are much better balanced , other poles worth looking at are the phamton himod and the evo8 himod , ive never used either but reviews suggest not as balanced as the extreme but still nice poles
