  When I first started WFP I used Purolite MB400 and then last month decided
  to give Rohm and Haas MB20 a go. Have found the Rohm and Haas is not lasting
  as long.

  Has anyone else experienced this.

  Cheers

haven't used r+h yet but have used purolite, dowex, and another brand (can't remember the name but I think r+h bought them over).  Some say purolite lasts longer, for me its the other way around, I think its down to what batch you get, I had AQUApure resin fom the US as well and it lasted for ages but can't get it now.
