been using a mk1 slx for 3 years, used as a main pole every day (we work in the rain/snow) and the pole only ever gets a clean once a week unless some grit gets in (in which case it gets flushed there and then). pole still going fantastically well and nearly as good as new.
we've got 4 of them, the youngest being 2.5 yrs old and as you would expect they are all still in excellent shape.
Vince Green - fibreglass used to last us about 6 months per pole, compared to carbon fibre the fibreglass is rubbish - get an slx, you will not be disappointed.
Gardiners - excellent pole, well done.
