if you were to keep your hair short i would say go for a light density..which would rule out a stock piece.
although a stylist can thin out the bulk (appearance) by around 10% it doesnt actually change the density. you dont want hair that is to thick on top in relation to your bio hair.best bet send your pics to john...

swiss lace is probably your best bet with sweat and exercise. attached properly if is nearly undetectable to touch...

from the side pics it looks as though you have good temple peaks. but sometimes those side pics are misleading and from the front you may appear to have a wide forehead.
btw nice toys ya got there!!! bikes and fast cars, GREAT combo!

if you wish to post a front facing pic and 3/4 side front pic i can try to do a rough mock up to hepl with a template design... you want your hairline to transition into your bio hair naturally and to straight of a hairline or one without appropriate recession that matches your sides makes it look off or unnatural. the links below should be helpful with what i am talking about...

not everybody agrees everyone agrees with that above advice. some feel if i am replacing my hair why would i want a receded look to any degree? i always say because you want it to look natural!

hope this helpful
