I have a slik tripod, http://www.bhphotovideo.com/bnh/controller/home?O=NavBar&A=getItemDetail&Q=&sku=278491&is=REG&si=inc#goto_itemInfo
i use it generally for still photography, but it says that it can support up to 11 lbs.

My question is can i put a high quality fluid head like the bogen/manfrotto ones? or something similar? Thanks

Click on that little triangle to the left of your post and ask pretty please if a mod will shift your post to the "Tripods, Sticks and Heads" section.

BTW, the answer is no.

I think I've seen some of the cheaper Bogen heads that are not ball leveling. One of those might fit on there if the threads are the same.
