Which Method will be best for me now ..

Honestly, I think you can take your pick.  Your hair is plenty long.  I would pick pinchbraids (I also do wefts), because with wefts in hair that is fine but lots of it, I get weft bumps in the natural hair because it is so silky.  If this doesn't make sense let me know. 

     Who's putting them in?  Do you have your hair?  Maybe you should get Dome style box braids and let us know what you think.

So I've been thinking about this question al lmorning while slaving away in the clean room in 100 plus heat.

I think you rtop layer is long enough you could do any which type you like.  And while its hard to say without a closeup of your scalp or a chance to run my fingers through it its looks like you are right that it is thick even if fine.  Since it looks to be in good condition why risk screwing it up with fusion glue? 

ify ou are used to haveing a weave why not mix and match?  do you do cornrows and sew for your weaves?  cause i thinking you could do the top with a thinner track method.  maybe the string braided tracks (is that malaysian???)?  and then stranf by strand at the bottom to give you some versatility in the way your style say pinchbraids?
and around the edges closer to your hair line (you have bangs right? lookslike it but it could be glare) a few itty bitty shrinkies with teensy weensy tips to keep it from being too choppy in the front.

but that's a bit over the top isn't it.

I'm still trying to decide on my method for my next next install.  If its going to be shrinkies or rings I'm going tohave to start tipping.  if I'm going to do any sewing onto tracks I need to take stock of what wefts I've got available.

Hopefully I've got enough hair to take my own advice and do something like what I just suggested.

if i can teach my mum ( or boyfriend, but judging on how he dyed my hair 2 days ago may not be the best idea :P) to do the back, then thats helpful..

I'm thinking about trying microrings.. I imagine they won't be too difficult for my mum or boyfriend to do at the back, and they don't involve heat ( once again i let my boyfriend straighten my hair once... painful ears!)

 

thanks for the advice i definatly need to experiment :D
