Any special reasons why this is? Usually price and weight increase with C rating, no? Granted, the differences are minimal.
I noticed that too and found it strange as you did. Yes, normally the higher the C rating, the heavier the pack as it is the 'density' of the battery that gives the extra discharge capacity.

I hope the company rep that comes on here can explain it.
