^^^ As above , stiff extreme if you want it to last , i moved to them in Jan 15 after an unexpected stroke , Alex was kind enough to send me a couple to reduce the strain when i got back on the glass , i wont forget that gesture as it was not asked for........I did ask him for an SLX , never got it.......he's a nice man , but not that nice
I ended up buying one myself , he knew i would once snared .
Anyway those same 2 extremes are still in daily use today for monthly cleans , i swap to an ultimate for first cleans but thats it.
