buy the blue lubical. use it for everything, it works perfectly. dont buy weight five that stuff is like glue. and dont worry about using two diferent kinds of lube, theres really no point.
why dont you make a youtube channel, buy one of these, video tape all of it. show us whats up. then take down this comment. Crazybadcuber doesn't solve in competition but we all listen to what he has to say.
Although i prefer the Original Aolong, the Aolong V2 Isn't any faster then a ZanChi (and mush more controllable) so you have nothing too worry about there.
Also if you feel your 2x2 is too slow i would get a MoYu LingPo, it feels a lot like the WeiLong.
Welcome to the forum!
The inner edge pieces, the ones that move with the corners, have awfully large parts holding them between the centers. I cant help but feel it will be slow. Not bad but just slow and maybe a bit clunky. I'm sure it will be smooth, they use nice plastic.
