There's nothing that feels like a Guhong; however if you do the 48-point edge mod on it, it reduces the noise signifiantly without dramatically changing the feel. Takes about 30 mins to an hour and a piece of sandpaper or a file. Much cheaper than buying a new cube!
Do you feel like the mis-alignment is due to the size of the cube? Many people prefer a very slightly smaller cube for OH, such as the Zhanchi 55mm, or the ShuangRen 54.x, or Weilong 54.x (one is 54.6, one is 54.8 I think, but can't remember which way round!). I find the Fangshi a bit unstable, personally, and use a 55mm Zhanchi.
If you
don't think the misalignment is down to size, it may just be your OH turning style. Watch Weston's new video on CubingWorld about getting fast at OH - it's all about practicing how to turn. Also I think Phil (ASmallKitten) made a vid a couple of years ago called something like "how I turn OH". Worth a watch too. Improving your style should reduce lockups and stop your fingers getting in the way of each other!
