I've read about Sphinx packet format and generally familiar with the way it works. But still you have to reserve some space for those tags in total packet size, which is an undesired overhead.
So even if you only use 3 hops, but system is designed to use up to 10 hops, then you'll have that overhead of 7 unused hops, assuming the packet size is fixed.

Assuming packet size is 512 bytes like in Tor, 7 unused hops will result in 22% useless overhead, not taking into account the rest of the Sphinx header. This might be fine for large packets size, but I think for smaller ones it is too much.
