If the pellets are slow moving, then what is the use of pellets?
Catching pellets like this, will not give a significant energy advantage
over taking the pellets with you (=attached to the starship) from the start.

Still you have to launch the pellets many many years in advance. This above
all is considered the worst problem for the "pellet-track" idea. It may not
be a technological problem, but it surely is a big ideological problem.
