Where to spend my Bond now

Olla boyz and girls.

I am looking for some advice. I am 51% WR (23k games) player who IS playing most of time only for fun (tanks like FV, udes, mouse, TVP and other variety of funy GamePlay tanks).

I am in clan which IS not active anymore.

So now i have a question. I have again over 15k BONDS. Are they worth to spend on 121b or not? I allready have Concept 1b and Also KPZ so i dont have to save fór them anymore. I really wanted Chief but this is not possible in inactive Clan and low ammount of BONDS i have now (i should had 57k if i didnt spend them on conc and kpz). And i allready have some Bond equipment (Also All of bounty upgraded).

So should i buy 121b or what to do with my Bonds now? 🙂 (I have Leo 1 so m60 IS not worth i ques). Or something else? (Dont say find a Clan, save 50k more, play active and then after 2 years bid fór Chief becasue IT wont be possible fór me). Thankssss
