The device that Donovan and I devised would make it possible to get tensions exactly to what you want on all sides, loose or tight. That will be exciting. Ill have more free time!!
I have had a tough time on this decision.. Personally I have found a tension setting on my LunHui that makes it very smooth turning, without the torpedo locks that you get when it is too loose, while the LunHui does take some getting used to because its hang ups are in a different place than most all other cubes, I expect Fusions to not have any real problems with locking from Torpedos. Based on the feel of cubes that Donovan has made me test out. I couldn't feel much difference between them at all.
