Redstone Destroy-Particle Fail

I've found a bug while destoying redstone. The particles of redstone are totaly new since the update 1.4.7.
I hate it

What I expected to happen was...:
I can destroy redstone in every version with the same texture of particles...

What actually happened was...:
The particles of the destroying are totaly new and very ugly!

Steps to Reproduce:
1. Place a redstonewire on the ground
2. Destroy it! That's all!
