They are just starting out as a team and want the same guns, Can you get 5 E1 cockers all the same as easily as you can get 5 Ions? I think not.
And i may be wrong, but they are just starting out in paintball with electro guns and so i dont think cockers will be a good idea with all the maintenance and setting up.
Dont get me wrong that cockers are great its just I think Ions will be a better choice for their situation.
