The-Plethora Posted March 22, 2012 Share Posted March 22, 2012 500 - 550 seems to be the general agreed long term limits. Quote Link to comment Share on other sites More sharing options...
Lee_e Posted March 22, 2012 Share Posted March 22, 2012 I thought 400-450 was on the limit ? I could of course be mistaken. Quote Link to comment Share on other sites More sharing options...
