When I'm doing 3 cycles, I'm always wasting a lot of time to figure out the best why to orient the edges (like how to pair them up, to orient may be 4 at a time). I don't really use any set up moves much...I just rotate it (I guess it's not a very good idea..)

How do you guys memo the EO and solve it efficiently?

And what is your avg for EO step (memo and execution)?
 
When I orient edges, I try to do 4 at a time, if not, I do 2 at a time. I memo EO by numbers, or visually, depending on the case, and I'd say it takes at most 5-7 seconds to memo, and around 10-15 to solve. You should always use setups to get 4 at a time, or you can do an 8 flip if you have like 6 edges flipped, and then just fix the 2 you flipped wrong. The 8 edge flip is (r R b B)x3.
 
I have just started blindfolded and average around 8 minutes (10 last week, 15 last month). EO is the easiest step for me and takes about 1 minute for analysis, memo and execution.

I know only how to orient 2 edges at a time and 4 edges at a time and prefer to do it on the U layer. If 2 edges are already on the same face, I just rotate the cube so they are on U. If 3 edges are already on the same face I add a fourth one.

I memo things like "all 4 on U-face after B2, then 2 on front-mid-slice after you turn R". This would orient (UF, UL, UR, DB and LF-RD)

Give me a few examples and I will tell you how I would group them.

I think it would be usefull for me to know a 12-flip. If almost every edge is misoriented, just flip them all and then flip the ones that were correct already again.
 
How about this one?

D' U2 R U R' B F2 R2 F D' L B' D2 F' U' B' L2 U B2 U2 B' D2 U2 L B'

scramble it like how you would hold your cube while doing BLD. I actually orient into UDRL group...so there are only 4 misorientated edges XD

I would do x2 U L (M' U)x4 (M U)*4 L' U' x2

May be..if there are many edges misorientated in a tricky way...you can just orient it to either UDFB or UDRL? hmm but just orienting more than needed is a good idea :D
 
For me, with orienting edges in the UDFB group, I would say to do R' F x2 z (R' F R F')x5 z' x2 F' R. I would do it the same way as you for UDLR.

I memo EO after EP and CP. Memo is around 5-10 seconds, execution around 10-15. I'm averaging in the mid-4's right now, with my PB in the upper 3's.

y' R U' R (M' U')*4 R' U R' y
y L U L (M' U)*4 L' U' L' y'
