Tyranid Guant progress

I finished assembly A-Z on 4 spineguants today. I was inspired by having purchased some hobby files and a hobby k,nife. Both of which are produced by games-workshop. I have to say they are good and my only complaint is I think the hobby knife blades should be sturdier and not as weak. I have not decieded on my exact army composition. I am content with guant assembly as there are so many to do. I cant decide what to make my hive tyrants but I am hoping to make a decision soon on that.
