early...i tend to agree with the thoughts on flaps....they need to be perfectly ventilated to replicate the growth pattern and density of real temple hair, then there is the issue of basically now having 2 additional hairlines that are fully exposed...
i attempted to improve upon his original design,,,,,but i also say scrap the flaps, but then he will not achieve the look he is hoping for....he would have to have a pretty recessed hairline done in order for it match the recession of his sides.
the first pic posted on this page shows just how recessed his sides are and thats with them being somewhat covered with the hair brushed forward....personally i dont think a slightly recessed hairline that has to reach that far across the front of his head and have to go that far back could look natural
