The best alg for flipping the DF and UB pieces is only a single move different to the one that shoots to BU
That makes sense once I try it. I was shooting UB with just M2, and then flipping UB and UF with M' U M' U M' U2 M U M U M U2, or flipping UB and DF with the same algorithm and an F2 setup move. I like your way better.
This is not center safe and dont work well on big cubes like 5bld.
Look-ahead. I think I finally start to understand it
I really need to slow down a lot to be able to find and track the next pieces while solving a pair. I think it never clicked before how much I needed to slow down. To practice, I now try to turn slow enough to see the pieces moving and follow them around (and not just glimpse at them flying by, hoping for the best).
The most surprising is how fast my times are when I turn super slowly during F2L... I think by finally realizing this, I can now practice my look-ahead and improve F2L stage.
Anyone relate to this experience?
Yes... but it's not quite that simple for me. I often find myself surprised at my times while slow-turning pairs and I definitely notice when I'm solving pairs fast I can easily get into "burst mode" with those dreaded pauses between quick pairs. But I do still have to change gears and execute the last layer quickly which I find tricky after slow-turning through F2L. It also still seems to hinge on me being in "a groove", slow solving pairs isn't a guarantee. Like Jason said, it's somewhat of a balance to be reached for me.
I'll be doing a LOT of slow solves for a while though, between breaking my F2L recog with new ways of dealing with some pairs and breaking my OLL recog with a bunch of new algs
Some are though and it's good to know which ones. I also prefer (M' U)X3 M' U2 (M' U)X3 M' in 3BLD because I prefer M' moves, but use M' U M' U M' U2 M U M U M U2 in 5BLD. That's fine because in 5BLD my slices are done like Rw R' anyway, so M moves aren't so inconvenient.
I don't know about a rule, but it's fairly easy to see what happens to the centres by trying on a solved cube. If you take a simple example like M' U2 M U2 you can see that the middle line gets taken out of the centre then restored the other way round after the U2. The flipping alg discussed above is similar because it also takes the form s U2 s' U2.
.My obliques suck
Which raises another important point. There are really three categories: algs that mess up centres, algs that are truly centre safe, and algs that are centre safe only after centres are solved. The flipping alg falls into the latter category. It does actually rearrange the centres, but keeping the pieces on the same faces, so it's OK as long as centres are solved. Just don't flip your edges before you solve your centres

Hi, Capetown-er. I was there just in august. I wish you a good comp.The next Cape Town competition has been announced ... https://www.worldcubeassociation.org/competitions/SpeedcubesCapeTown2017
This will be my 2nd as a Delegate and my first as sole Delegate. To be honest I feel a little nervous about being the sole delegate. In the previous competition I had a more experienced Delegate assist, and this time the buck stops with me so to speak. I'm looking forward to taking the reigns but I also want to do a good job with it ... so hence the nerves
A little nerves is probably exactly what you need.The next Cape Town competition has been announced ... https://www.worldcubeassociation.org/competitions/SpeedcubesCapeTown2017

You'll do great! Good luck.
