I was averaging 20 seconds back in 2013. I bought like 10 cubetwist square-1 and square-2 since they were IMO the best out there (compared to th MF8 V1 and V2 and the really crappy Calvin's SQ1) and I wouldn't know if they would keep produce them.
Now, late 2015, I'm tempting to go back to SQ1...
I've been cubing during 2012-2013, square-1, 2v2 and 3v3 mainly. Since then, what has changed in the regulations? I'd like to come back to speedsolving! Is it true that stickerless puzzles are now allowed? All stickerless puzzles?
I have a ShengShou 8x8 and a ShengShou 9x9 (both black) to sell. They're lubed and tensionned. The 8x8 has CS stickers and the 9x9 has Izo stickers replacement. They turn great and were barely used (1 year old).
I sell both for 90€ shipping included to Europe.
I agree, the CubeTwist is much better. I have all the square-1, and IMO Calvin's is the worst. MF8v1 is more stable, sturdier too. And I average 20 seconds with the CubeTwist, and didn't get any pop for weeks. So...
No, not at all. Once you get used to the cube, it won't pop. I average 20 seconds at square-1, and after having tried all the different brands (GuoJia, MF8 v1 & v2, Calvin's), the CubeTwist is the best IMO. The Calvin's is the worst (overshoot, and is basically a MF8 v1).
You can't go wrong...
