I like Stuor blades. For the money, it is very well constructed. I like their Viscaria clone, fast. ZJK clone is good too. However, I do not like their Harimoto clone (too slow) and Long V (also too slow to me).
I don't expect their blades to play like the original.
Again for the money they charge, those are good blades to put two sheets of rubbers on and play for several years.
I personally like cheap blades because I like to EJ a lot. By EJ'ing a lot of cheap blades, I have found the one where I like the speed (not too fast and not too slow) and the touch. I doubt I could have done so EJ'ing Butterfly blades.
