May i suggest demon hunters? storm bolters and halberds?True but in the end I don't expect to go amazingly to far with this army. It probably won't pass 500 pts at best, kill team is probable. More just a fun little exercise in conversion for a IG beastmen army.
In truth though I have been looking more into the Tau and they will probably be the final destination of something "special" in terms of an actual full Beastmen Based army.
