2006? time flies but adhesives get better, i just used the standard set single part flex and i found it to be rather good, also used the fast set and it has a decent bucket life it does not go off too fast..unlike tilemaster which is very popular in wigan /bolton i wont use it anymore due to it going off way to fast also the quality varies too much for my tastes and the white rapid is way to rapid not to mention a bit to orange.
