motor kv and amp draw for 4s buggy

i am thinking of 2-3 motors for my rc8 buggy and would like thoughts and opinions on my choices

i am thinking of either a 1512 2.5d (2050 kv) or a 1512 2d (2600 kv)

these are rated at 78 amps and 125 amps




if i am geared for the same speed will i still draw more amps with the higher kv?

i think so as total watts = v X a


will the lower kv motor run cooler



i may also try a 60mm (2000 kv) medusa as i have heard good things about these
