Hi Marcelo, If you can stretch to it, get two systems. ....that way you have a back-up system in the event of some un-foreseen disaster with one [such as sudden profuse shedding which can happen at times, though is usually rare] Why not just go for a lace base [French or Swiss] for breatheability, with a strip of Poly around the sides and back..the poly is hard-wearing and easy to clean so you just have to front hairline area to ` worry` about in terms of clean-up`s .... I think a lot of new-comers to the wearing game find that combination is pretty easy to work with.
Skin systems have their pro`s and Con`s , as with lace.... it can be a bit of a minefield coming to a decision, but whatever you decide, I`d recommend you get two systems.... at least if one develops issues, you can get a replacement order and the 2nd system will keep you going until the new one arrives. Even in the event that a stylist didn`t do such a nice job on one, you can go to another person and have the 2nd one styled immediately.... we all have our preferences, developed over time and from experience -- you have the learning-curve ahead of you so no point stressing out too much at this point ....... I think for a new wearer, a free-style system, lace base with a poly [skin] strip on the sides and back is very easy to work with...you can ` play-around` with your hairstyle that way and the clean-up`s and re-attachments are relatively easy. Regards.
