If you flash. it will overwrite system data so everything you de-bloated will be gone most likely. If the rom is de-bloated, you will still be de-bloated. If you load a full rom like the DL09 full, all the bloat will be back. The DL09 leak is rooted and de-bloated. The full DL09 is not rooted and not de-bloated.
make sense?
