I though about using warp spiders but my issues are the following. First they will be the only infantry on the board if I choose to deploy. Second my deep strikes will probably result in mishap, (cause that's how I roll!) so I feel vypers might give me more control. If I deploy or put them in reserve even if they come out on turn 5 they can still do their job (spamming strength 6 shots on infantry or light vehicles). I plan to turbo boost the vypers until in range and at 24 it gives me breathing room to keep out of assault. I bought 3 vypers for 35 bucks on ebay so I don't plan on buying them retail. I guess the other question is if having the 3rd fire dragon squad even worth it?
