My final Lipo choices for Flux. What say you?

Ok after spending way too much time going through Hobbking, trying to decipher all the menus and crap AND what actually was in stock, this is what I found that seemed like it work work well.

Do I go all out and get the new nanotech turnigys and go for the insane 6S power that i've never experienced before?

Or do I play it a bit safer/cheaper and get non nanotech with just 4S which im familiar with?

Or do I get this 6S non-nanotech Turnigy from the USA with higher C output?

I guess im stuck ordering from across the sea as the USA warehouses have squat in stock, so i'm gonna have to pay arm and leg for shipping. How long does this EMS Express to USA shipping take anyway? Or should I just wait to get something better in like these?
