HehWiggy...I too was concerned about the very thin area in the crown but once it is cut in you hardly notice it because the hair will probably not be that long on top and will appear thicker depending on how the unit is cutin....However I do have some concerns about the placement of the crown and I have had this concern for quite sometime...it seems to always end up in about the middle of the head evrytime I order a stock unit freestyle...I tend to agree with Aussieboy and my next orders will be No visiable crown because I just don't like the placement and how the hair falls in that area,,,I guess you also need to be aware of the type of style you want...which in fact has been brought up on this thread. You'll be fine and the density of your unit for Toplace is pretty high...I my self only go 65%...but I am 60 years old...You should be fine...not to worry you can easily conceal it depending on your hairstyle...welcome aboard...Cheers
