Safest thing would be to magnetize both the head of the big guy and the rider weapon options so you can use 4 out of 6 options (and a spare rider you can easily convert in a icebrow Hunter if you feel inspired). With the mournfang pack it's pretty close, both options are really good but given the recent buff to clubs i'd go for them , more consistent damage and the ironfist is a nice bonus (also it looks so good).
