We are getting all new draw slides in our 20 year old cabinets. The cabinet guy said that he uses Blum standard drawer slides. I have deciced (because of you guys...peer pressure) to get the full extension. We currently have the slides on the sides down in the corner (we have European cabinets).

My question is, what full extension Blum slides do I need to get so that later I can add the Blumotion if I want to?
