So the 4 jetbike + 2 vyper set-up or is a more cautious approach giving you BM ability at range with reduced possibility they fall prey to casualties / suppression. Is there a role for 6 x Jetbike or a 6 x Vyper selection?
First point to question is whether you are playing the rules + 2008 amendments, or using the additional suggestions incorporated in the 'Handbook' (which give the Jetbikes a 5+ save). Second question is how you intend to use the formation.
I use the 2008 amendments only, so the Jetbikes and Vyper all have a 4+ save - thus the formation composition depends on how I want to use it. As I said earlier, the Vyper is only there to be able to place a 'Shooting BM' in preparation for an assault by another formation. As such I want to maximise on the support potential and the Vyper is not as good as the Jetbikes in this respect. Irondeath's point on redundancy is that being the only Vehicle in the formation, the Vyper becomes the automatic target for any AT shooting and consequently likely to die quickly. The answer here (as for all Eldar formations) is to keep hidden until needed to avoid being shot at.
As to an all-Jetbike or all-Vyper formation, being a LV means that the Vypers can be shot at by everyone and are consequently more vulnerable than the Jetbikes. However, being infantry makes the All-Jetbike formation slightly less vulnerable and means that is almost as usefull as a mixed one.
