Now Hermowninny:
First, I agree with everything that has been said on this subject.  
JKR tells us that the spell would have been more powerful if Dolohov 
were able to use the incantation (can't quote a page, but it's at the 
end of the book when Harry goes to visit the others in the hospital 
wing).  I just have a thought to add...  

When Dolohov usses this spell (slashing wand movement with a purple 
light--I think, sorry, don't have my book) on Hermione, he has been 
silenced.  However, he uses this same spell twice more.  Once against 
Harry (I believe Harry used "Protego" to shield himself) and I 
believe the second was against Serius?  I'm not sure of these 
details, but they take place about two pages after Hermione is hit.  

Anyway, my point is that the spell is described exactly the same way 
each time...  slashing wand movement, purple light, etc.  Harry even 
states that it is the same one used on Hermione.  Never once does 
Dolohov utter an incantation with this spell.  He has regained his 
ability to speak when he uses this spell the second and third times, 
but still no incantation.  If the spell is so much more powerful with 
the incantation, why doesn't he use it?

What gives?
