As GW produces neither Fenrisian wolves or thunderwolf cavarly there is no offical model or associated base size. This is potentially problematic as player may not agree on what size to use.
Canis uses a 60mm base however he is a special character, he however is not a thunderwolf unit member.
As Thunderwolves and Fenrisian models are cavarly type do they use a standard bike/cav base?
There is a substancial footprint when using models on a 60mm base that can be exploited to control a much larger area of table particuarly when used as a unit.
Would it make sense to have an offical ruling on the "correct" base size of these units set in place ahead of the tournament?
