Brotherlocs are just larger than the traditional sisterlocs. I have no idea how many I started with, but it was a ton! I researched how to retighten locs using a latch hook and at the time (6 years ago) was able to find a really good photo tutorial. Now they are very hush hush about price, but I will tell you that I paid $500 for my install and not to mention going to them for my first couple of washes, it can be pricey. I am definately going to loc again sometime in the future, but this time I am going to do braid locs with micro braids and latch for maintenance. I personally saw no major validation for the price. I am glad that I didn't get them any smaller. If so, it would have been awful to maintain myself.
As far as the rotations go, 3pt and 4pt refers to the number of times you have to insert the tool into the loc. For instance for your first turn, you would enter the base of the loc from back to front, the next, right to left, next front to back and lastly left to right to make a full rotation. This ensures the there are no gaps left at the base which can weaken the loc over time.
As you saw in my fotki, I treated my locs just as i did my loose hair as far as styling. I dyed, layered, and roller set just to name a few. Ultimately, I ended up with buildup in them and lint over time and during my hormone induced pregnant state, couldn't take it anymore. I was going through some life changes at the time too and just wanted an extreme makeover.
