Well, almost but not all. Some of the default ones are just to hard to wriggle into what I need, so changes are needed. Though not altering them beyond recognition lol, just enough for my purpose.
Index, boardindex. messageindex and display do get a makeover though, all using common subtemplates located in Common.template.php, a new one. I try to streamline boards(messageindex's child boards along with boardindex) and any topic index(messageindex, pm index and replies/unread template, prob. also profile template but haven't got around to that yet). then theres Display which use a post subtemplate, this is also used in the pm template...and so on. Using common templates like this simplifies the code and also the CSS overall.
