Hi LTB,
Good questions. Many people make the transition from a topper unit to a full cap and say that wearing a full cap in easier than wearing a topper. Reason: you don't have to blend color and density with your own hair like you do with a topper. The downside is keeping the nape of the neck well attached because that area moves and the bond must be kept strong in order to avoid loosening. Our full cap guru is JRob. Here's a photo of JRob with his full cap wetted down:
