I don't think flow-caching is necessarily due to CEF. Even on dinky 2500 & 2600 series where you don't run CEF, load balancing over multiple links uses a flow-hashed method.
For the 312534906703247th time: Switching Balancing per- Process packet Fast dest (net) Flow flow CEF* src-dest pair CEF** packet * by default ** with "ip load-sharing per-packet" on incoming interface
If you want per-packet load distribution you have to specifically enable it by saying "no ip route-cache" on each interface.
If you want to crater your router, sure. Otherwise, I'd consider one of the other options. S
