Did you read what Tom Kyte always write about this one? "BUT - do not use multiple block sizes for anything other than transporting data from database A to database B where the block size in A is different from B.

The cases whereby multiple blocksizes are useful are typically limited to benchmarks, old wives tales, and very exceptionally rare conditions."
