A weapon for all ranges and modes?

Think that with these three bags I should have the best advantages for all modes and ranges?
Bag one: AWM/Desert Eagle- Long ranges/ For S&D and TDM
Bag two: Scar-Light/Desert Eagles- Medium ranges/ TDM, FFA and S&D
Bag three: XM1014/Anaconda- Short ranges/ GM and S&D (surprisingly effective).

Think I should have everything pretty much covered?
Also it has taken me ages to get these bags together without spending too much on ZP so be nice.

*note for bag three I originally started using an AK-47 but found it too difficult to use it and the Scar-Light*
