What motor to run

[SV6000]

Hi all in RC Monster forums Can you please help me with a decision as to which motor to run. I have a G3R that i wanted to run a Schulze and Bigmaxximum but with the exchange rate at the moment it works out to be very expensive (Just over $1000) I was thinking of either the 1527 1D or the 1521 1.5D. The question is what ESC. I don't want to run a schulze because of the price, and i have had a lot of bad luck with MGM Or should i just use a 1515 1Y MMM combo
So my only real options are the MMM or the new Tekin RX8 wick according to them is rated for 200A. Has anyone had anything to do with these controllers. What do you guys recommend.
