Every day's a school dayBAL Fastflex is the most flexible adhesive there is. S2 isn't really a measure of flex, but more of flexural strength (i'm told anyway)
Some situations call for massive bond strength - so use TM Ultimate for that.
Others call for more flex - BAL FastFlex for me in that case.
I'm with Andy Allen on this one. GT1 with the BAL grout too.
