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.
