Not really the attitude for sub-1. But hey, it's possible.
Bare minimum tips:
*Stick to M2, it's good enough for sub-1.
*Learn a couple of algs for specific/tricky cases. I.e. Awkward corner targets, learn to recognise when an A-perm can be done etc.
*Watch this video, and learn these algs taken from
Zane's progression video:
T-perm flip: x' R2 U' R' U x R' F' U' F R U R' U'
Adj-edge flip: R' U2 R2 U R' U' R' U2 r U R U' r'
Mono flip: [R' D R D' R' D R] U' [R' D' R D R' D' R] U
Y-perm: R U' R' U' R U R' F' R U R' U' R' F R
*Master your memory method. Can be done through practice or by adding extra tips such as: incorporating all the senses into your memo, adding colour to images, using visual memo, etc.
Oh, and practice. Practice practice practice until all your algs and set-ups are automatic and require no thought whatsoever.
