I have skin pieces. lace ones, combos of lace front skin base, and skin front lace base.. lol. I been trying diff combos out. The matter of comfort is individual.. Some people don't find skin hot or any discomfort.. the thing with skin is,, if you are going to wear it, you have to bond it to your whole head.. Meaning that I don't recommend only using tape/glue on the perimeter only.. U should coat your whole scalp with something, even if it is got2b glued. When u bond the skin to your entire head, there is no room for air or heat to develop.. you are basically sealing off your scalp.. in turn it feels more comfortable because there is no air inbetween ur scalp and thinskin to generate heat and sweat / oil etc. But this might raise your overall body temperature somewhat depending on how big the unit is, because you are blocking off the top of your head where heat escapes your body quickly.

Lace can be easy or hard to deal with.. same with skin.> it depends on the adhesives you use on which.. With lace you could use these non residue tapes for an easy attachment and removal. and with skin,, you could use got2b glued or weak tapes depending on the type of skin.. with the new generation you are going to have to use liquid adhesives.

The pros of skin for me are:

No hair coming out the underside of the base,
Dont' have to worry about glue going t hrough any holes etc.. u can wipe the skin off etc.
Potentially easy attachment removal if using something like got2b glued
if you can get it to look right.. you don't have to worry about any grid pattern in different lighting conditions

The cons

Limited amount of adhesives and attachment methods you can use.
The ventilation doesn't seem as natural as with lace knotting..
Can be hot to wear,, unless you bond to the entire scalp.
Not as comfortable etc
Sometimes the hairline never looks as good because the skin material just doesn't blend right with some peoples skins.


Lace-

Can attach it a million diff ways with diff types of tapes etc..
can still use got2 glued on it
Usually better ventilation, especially with hairlines
When finding the perfect lace that disappears probably looks the best at the hairline
more comfortable to wear. You don't have to do an entire scalp bond

Attachment and removal can be a pain in the ass or easy depending on what you use. If your using an easy to deal with tape than its easy.. if your using ultra hold all over the clean up will be more of a pain.
