Mixture of Layer by Layer and Fridrich. Primarily LBL.

I know perhaps 10 OLLs and all but 5 PLLs.


What should I start first to drop my avg time from 35 seconds to lower.

It looks as though you know enough OLL and PLL to do a 4 look last layer. The thing is that those 4 algs that you apply to the cube probably don't take a big percentage of the time you use to solve the cube.
The thing that will take up the bulk of your solve time is the F2L so start working on getting that faster.

You can always learn new algs, but looking ahead is a skill that takes a bit more time but has a bigger payoff.

learn more algs.

I only know like 8 OLL and 17 PLL out of the 70 or so total, and I do 3 look last layer. I have to agree though, f2l is what kills me, so I would work on that.

what do you mean, "70 or so total"? please clarify.

57 OLL + 21 PLL = 78 algs.

xcool: What are your averages (approximately) for F2L and LL?

I think if you moved away from LBL to a more CFOP approach that would help your times alot. Obviously you don't want to learn all the fridrich F2L algs... that's insane! Try reading some of the pages that describe intuitively pairing up and inserting c/e pairs:

also since you obviously aren't doing a one step OLL you might find it useful to look at some of the techniques that orient LL edges before or as you insert the last c/e pair for F2L.

this step can be really intuitive if you pay attention to preserving your c/e pair and learn the basics of intuitively orienting edges.

I think you'll probably find that a few new techniques and ideas will go further than alot more memorised sequences.
