Tipping Question

I'm still trying to figure out what method and what hair to use when these GL's come out in november!  There's so much info on here from you girls, its so awesome!  If I were to tip my own hair does that hair come off the wefts? or is there a certain type of hair i'm supposed to buy to do this?  I don't even know if i'll try my hand at tipping myself, will probably go with the pre-tipped.  I'd really like to try the protac since its seems easy but I just can't grasp how that is sturdy at all or undetectable?  I've seen your great pics on here and they look awesome, but my luck, mine wouldn't look like that!  Also if you have or use protac, how do you get highlights in there?  i'm sorry girls, so many questions.!

Thank you!  Now if i do the tipping myself, do I use weft hair and just cut it??

I think I'm going to just do the individuals.  Was thinking of doing the shrink tubes method.  Course I'll have to practice first, I've already warned my sister that she is going to be my installer for the back of my head! I'd like to get the pre-tipped but I can't find anywhere that has pre-tipped Bohyme (from what i'm reading from you guys its the best?) but all i see is wefts, so that why I was thinking I'd have to tip them myself.  My hair is brown, but with some blondish highlights and I just think that it might look best if i do an individual method rather than the protac
