Edges then corners question

[liquid_helix136]

Hey, my main goal is to try to get under a minute, without memorizing a ton of crazy algs, as Im not/dont plan on getting THAT hardcore into it, but I do enjoy it.

anyway, so far i do the white cross first, F2L method, then the basic beginners method to finish the last layer by doing the yellow cross, orientating the yellow edges, and then positioning the yellow corners, and finally orientating the yellow corners to finish the cube.

My question is, is there a method/list of algs that will orient the yellow corners WITHOUT disturbing the yellow edges? The part that tends to slow me down the most is going through each corner and orienting it through the Ri, Di, R, D, Algorithm, over and over, and then spin the top, and repeat, until all corners are completed. Right now I have a good solid 1:30 solve. anyway any help or direction to a method/list of algs that will help me out with doing these corners quicker without messing up the edges would be appreciated.

Im not looking to become crazy fast, and dont want to relearn doing the corners and then edges, just trying to be a little faster.

Ive searched but didnt turn up anything useful.

Sorry for my long essay post

badmephisto's beginner tutorial on youtube has some good algorithms for this

If you change your order of operations a bit you can use the Sune: R U R' U R U2 R'. This algorithm twists three corners clockwise. Doing the algorithm backwards (R U2 R' U' R U' R') twists three corners counterclockwise. With these two algorithms you can fix any corner orientation case more efficiently than the R' D R D' method (I'll leave it as an exercise to you to figure out how - hint: you never have to apply these algorithms more than twice for any case).

These algs do move edges around, but you can get around this problem by permuting edges after solving your corners.
