The stock Hori Hayabusa joystick in a Hori RAP4 Kai isn't bad but it isn't perfect. I found on some games it isn't as responsive as it should be which is bizarre given it uses Omron microswitches. I also found it a little too loose. It improved with a KOWAL Hayabusa Octopus Octagonal Restrictor Gate but I swapped the whole thing for this Sanwa JLF-TP-8YT-SK and it is definitely superior. The engineering is better, it's more responsive, it's tighter, smoother and more effortless to use. I've used it with a Sanwa GT-Y Octagonal Restrictor Gate. I was an Arcade King during the 80s / 90s and have used many joysticks on many different machines. I play games using MAME on a Windows PC like Nemesis, R-Type, Truxton, Street Fighter various versions etc.
Many thanks to Arcade world for having such an extensive range, speedy delivery and for keeping the arcade arena alive!
