First robot build - Trident (FW) Need help plz

[Doodle2411]

So, yeah...
One of our members left the team, so that is 4 of us left.
So for that person and other roboteers in the forums I'm going to say these 3 things.
1. Even though all of our work has been posted under my username, I Consider it to be a team forum poster, I'm just the person who posts it.
2. Any future robots we planned, will be shared, meaning we all build one robot, 1 ant (siren), 2 beetles (unnamed) and 1 feather (trident). The heavy (posiden) will be built later on once we have the money.
3. Even though people have different opinions about things, doesn't mean we will always go with your ideas and suggestions, sure it may have a fault on the first match but the whole process is trial and succeed.

Other than that, if anyone has any idea what weapon type (pneumatic, springer or batteries) would be best to flip all featherweights and if possible the house robots and if you have any ideas for the interchangeable weapons, please reply

Thanks for the support
Many thanks
