DB_BLOCK_SIZE

There is a lot of theories. Do you use 2k,4k,8k... Oracle block size? We're running Oracle financials and soon Oracle manufacturing. We have a relatively small database, 16 gigs. But we're doing a lot of full table scans. Since our block size is 2k, we're planning to upgrade to 4k or 8k and there is where I need your knowledge... what do you think is the better guess? I don't want to start again next week-end!
My DB_BLOCK_BUFFERS is 51200, so 100 megs of memory and the hit ratio is around 98%.
If I put 4k, I will have 25600 DB_BLOCK_BUFFERS

.....    8k, ........... 12800 ................
