Not sure if this is the appropriate thread for this question, but what do you guys all think is the best cube to get for big multi blind attempts? I just got a 7/7 [49:30] PB on my first try coming from a previous PB of 4/4 [26:50], so basically I'm getting really excited about multi blind. However I only own 7 3x3's, and I'd like to be able to eventually attempt something like 12-16 cubes. I'd really rather not make a bulk purchase of a bunch of cubes that are more than 10$ each, but I also don't want a cube that is going to perform like a guanlong or worse. I guess a guanlong would be my last resort if you guys don't think anything else sub-$10 can beat it.
Just looking to hear some opinions backed with reasoning! Thanks
