Here's my little remark:

100 Hz is _second_ best to 50 Hz (which sadly most monitors/gfx cards don't support). At 100 Hz however, you will _still_ see more jerkiness than at 50 Hz. While scrolling is smooth, you will see the last frame a bit like a shadow(check with e.g. poing on WB, you will see the ball twice at certain speeds instead of once like in 50 Hz). This is because each frame is displayed twice instead of once. Even though it happens at a high frequency, somehow the eye will pick this up and register this little bit of jerkiness when directly compared to 50 Hz.

This was also a problem on the first 100 Hz TVs that came out. It manifested itself on the scrolly text, e.g. on the weather channel. It made some of the text unreadable at certain scroll-speeds. The companies that produced those TVs added some weird complicated digital processing to get rid of the effect on 100 Hz TVs, if I remember the story right....

But apart from that, 100 Hz is definitely the way to go. The little program called "refreshlock" might help you fiddeling with refresh rates, especially on other emulators like winvice, that don't have auch a nice manifold of options that WinUAE has.
