I'd get a WNNN as it has a pocket so you can take out the snap in insert and just stuff the pocket during the day (I have used them like this in the past) I personally don't like WNNL very much - they are slim, but I find them less absorbant than my other fitteds unless I boost them.
I actually have a WNNN (new style), WNNL and some WN wraps that I am selling at the moment if you wanted to try some cheaper before ordering customs - that's what I did and I now love my custom WNNNs PM me if you would like details.
