1) Happ Rotary joysticks. Can I just spend the extra money and put in one or two rotary joysticks in my 4 player panel. They look like they are based on the Super's design, do they perform the same or does it have negatives to use a rotery for regular non-rotary play?
My main reason to include rotarys is to play Ikari Warriors, did that game have two rotary's, cant seem to remember. Whats the best situation, no cost concerns.
(I don't have a happs rotary but I think:)
You might notice three differences with either happs rotary from the normal super.
1) The handle will spin. duh!

Even the supers spin a little, but I imagine the rotaries will spin easier. So depends if you don't like the feel of a "loose" (ie easy to spin) joystick handle....
2) You might notice the extra weight on the bottom of the rotary joysticks.
Very little difference in speed (actually, inertia), but some people will notice.
3) You need the control panel to be a little deeper to fit the extra stuff on the bottom of the rotaries.
2) HighBall 3" trackball or regular 3" trackball? Which is best? Barring the extra layout space a highball takes, is there any games that doesnt work well for a highball?
Prethanks.
I also don't have a high ball (I have the high lip).
Highball is probably better, but if depends on how you use the trackball. If you like coming from a low angle and hitting the ball low, and carrying your hand onto and over the ball, the original might be your cup of tea. If start with your hand on the ball, or only hit the top of the ball, or come from a higher angle (~45 degrees), the high ball probably is better.
Like Lilwolf said, though, betson and wico also sell TBs for cheaper. (Unless Happs' is on sell, then they are about the same). Also, I got my happs high
lip when it was on sale, so you might want to see if it still is on sale. It is a little different than the original happs 3".
