Disana wool overpants advice

astroMom

I just bought some Disana overpants hoping to use overnight.  However, I have heard conflicting info on how absorbant they are.  It sounds like they get more absorbant over time, so maybe that is the reason for the polarized reviews...you have to wait it out?  If they do better over time, should I start out using them a little during the day then transition to nights OR should I lanolize first?  (Their website/tag doesn't seem to indicate lanolizing first but GMD does...)
