I think this comes up every once in awhile and people usually say Comp or Supers, but my MKII and MK3 with the factory sticks were neither and I posted pics in a thread just like this one a year or two ago. After looking at them, someone came the conclusion that they were a Comp style that Happ doesn't make anymore. I'll note that when I put new Comps in my MKII, they were shorter than the original sticks.
I'd post pictures for you, but I'm out of the country right now and won't be back for a month or so.
For what it's worth, Comps with the upgraded springs work great.
What are these upgraded springs you speak of?
I have a buddy who is a MK III nut and after playing my machine (I have the happ competitions) he insists the joysticks "just arent right". For instance, he has a real hard time getting his fatality moves to work and sometimes during game play he has some issues pulling off certain combos.
I cant tell any difference myself but it has been a long while since I last played a dedicated MK game.
Check with Bob Roberts. They are upgrade/stronger springs for about $1 each.
OK well who is Bob Roberts and how does one contact him?
The Mysterious Bob Roberts
by Andy R
Bob was born in Louisanna. At the age of 2 he was abandoned by his parents and raised by the Operators of a local arcade, where he learned to speak their language and interact with other Operators of other arcades. By the age of seven he showed promise as a child prodigy and composed his first work, The Magic Fluke. (Hollywood eventually made a movie about this part of his life called "Dances with Operation Wolf's")
By the time he reached 14, he had found Mrs. Bob, and they were soon wed, which worked out for her because people could never figure out why she was called Mrs. Bob. By 21, Bob had amassed a fortune in Atari lighted pushbuttons and 1/2 ohm resistors. Had it not been for the accident in which he dropped an Electrohome G07 on his foot, he might have ruled the 1/2 ohm resistor market. But it was not to be.
5 years after his 21st birthday, Bob turned 64 years old (marriage will do that to ya) and he decided to retire. January 1st of the year 2000, Bob's business will officially be sold to the Greater Louisianna Waste Disposal Company, who is turning his business into an electrocution related theme park for criminals on death row.
(I know there are alot of years in there that I kind of glossed over, but Bob is a very humble guy and I know he didnt want me to mention anything about the time he saved the planet from starvation by inventing sliced bread, or the time he invented 'ice'. Thats just Bob...)
