So, I've been cubing for about a little over a year. I got my first Rubik's Cube in Sep. 2013, and have been improving my collection since then. I have a very good 3x3, a Dayan Zhanchi, and I'm getting a FangShi ShuangRen tomorrow, which may replace the Zhanchi as my main. However, my 2x2 is a very poor puzzle. It's a Shengshou model that I bought along with a bundle of higher order puzzles when I considered getting into 4x4 and 5x5. I have found a main for all the other puzzles that I like very well, but I'd like to have some suggestions on a good 2x2 to get. A friend of mine has a Dayan 2x2 stickerless, and I like it quite a bit, but it's been broken in very well. I need a fast 2x2 so I can get better times (On my 2x2, I average 11-13 seconds, while on my friend's Dayan, I average 7). Any suggestions?
