What is a good 5x5 method for intermediate-ish solvers. I can solve the 5x5 in about 4 minutes (or something) using centers normally, and then pairing up the edges one by one.
I recommend starting to learn advanced edge pairing or something like that.
You should try to get your centers down, by doing something like this:
First Center:
middle center, and 2 edges to make a 1x3 bar. For another 1x3 bar, and insert it. Then form a last 1x3 bar and insert it to complete the white center. Do this for the rest of the centers, and then get quick at doing commutators for the last 2 centers, i.e. 2 center piece flip.
For edges, try
this. I use that method, and the center method described above, and can get about 1:50-2:05.
