Various VF4 questions

Hi guys!

I would like talk about VF4 aspects which seem not to be cover yet.

-Are "collision detection" when you are near ring border are improved?.
This was an VF3 aspect i dislike cuz sometimes it was frustating!
Especially about roll near ring edge who seemed sometimes hasardous.
When i see some ringout they seem very DOA-ish with their big bound!

-How are music in VF4? I am sorry but i think some VF3 tune are very cheap.
does it same style,or more elaborate?

Please sorry my poor english, i hope you understand my thread ^^
