DB2 in 64 Bit Mode and Hiperpools

A recent client of mine is still using Hiperpools - while in 64-bit mode (and with > 2GB of memory on each LPAR).
It is my contention that they would save CPU, and probably get better buffer pool effectiveness, if they switched to a judicious mixture of virtual pools and data space pools.
Would any reader care to relate their site's experience with this sort of reconfiguration?

This client is on Version 7 - and I expect them to remain there for a while. I do know - from IFCID 225 (Statistics Trace Class 6) - that they can't replace the whole of their current hiperpool inventory with virtual pools. So some mixture of data space and virtual is inevitable.
