Best for huge object dif or dts ?

Wath do yo think that is the best for a huge object without collision?

Example with kork:
1:1000 or more

DTS works fine?
DIF - i read that its best for big objects but i can disable collision for a specific dif? I found this treath www.garagegames.com/mg/forums/result.thread.php?qt=25559

thanks.
