User blog:Motombo/M417 SB, Renew or not Renew?

Hello guys I need an opinion here, when my country's CA get rid of hackers, I will buy some NX(approximately 100.000) and I'm thinking to buy that stuff

Recon Vest

Cyclops Bandana(not released yet)

Anti Flash Googles(not released yet)

G36E Valkyrie 90D

M-200 Ghilliie/M107CQ SE 90D (both not released yet)

MP7 MOD 90D

And then I'll have more 50K~ NX

I have a M417 SB 7D that i got from Myst N case of a promotion(for free i received 7 cases in the Cristhmas)

So, how many renewal kits i'll need to gain approximately 90~100 days?

I used it(stealed it) and i really like then, but who's better, REC7 Rangers or M417 SB?
