Bald in TO

Hi there, I am on my 40's, have been losing my hair for almost 15 yrs. now. For the past 3 years I am using Toppik which has been working great for me, however since my hair loss continues and I am now a well advanced NW5 Toppik is not effective anymore specially on the hairline... the fibbers clearly show on my scalp??¦ and there is not enough hair left to cover them. So now it is time for the system, I knew I will end up wearing one and tried to delay it as much as I could but no more... there is no way I will shave my head since it doesn't suit my face and looks. The advantage of the system would be ppl. wont notice a radical change since they are used to see me with 'full hair' wearing toppik... My main concerns about wearing a system are: 1. How realistic and undetectable can they be? is it possible to get a low density and high hairline level that would suit a 40+ yr. old normal hair look? 2. How does it feels wearing the system day and nite? Do you feel it all the time on your head? How do you manage to sleep with it? 3. How much maintenance on a daily basis does it require? Say I have to get ready in the morning, is the hair a mess and I have to spend hours fixing it? Would appreciate your comments....
