iv only tested this gun and i dont see the need for any upgrades
Strengths:
Fast , light ,quiet, accurate, good distance
Weaknesses:
Nothing that i found, besides price
Review:
Testing this gun was so cool it was soo light that when i was snap shoting i thought that i was going to lose the gun, i think a phantom is heavier than this gun. Another thing that is good about this gun is the distance im on a rec ball feild now and im hitting people half way across the field
Conclusion:
If you have the money and your looking into buying a timmy this is the one to get
