Since you're turning 1 vector into 1 output value, you could also use a
gr_sync_block and prepend it with a gr_stream_to_vector. That
automatically takes care of aligning etc.; if you use a sync_decimator
you're not guaranteed to get N samples every time.

This should pretty much be the simplest solution.
