hey guys its time to replace the axial .28rr 2 in my savage. Thinking about going with the picco boost 5tr .28 ps, the nova plus .28-7ps,or the OS vg .30. The nova is a bit expensive so I've been learning towards the picco or os the os only comes as a roto which I prefer a pull so I've been leaning towards the picco boost. I've never owned a picco but have heard mostly good things. If you have any experience with these engines please feel free to give you opinion. Looking for honest non bias opinions. Thanks in advance for replies.
