Minimum spec ESC for 17.5t motor?

I have a Trackstar 60A, would a 120A Fleta or similar ESC make any difference. I understand that it may have more features, but would I be missing out on any performance?

Higher end esc's would have lower internal resistance = higher speeds. And maybe from a stop, the 17.5 might draw more than 60A.

Thanks for the reply. The Trackstar/TORO 120a ESC has a claimed internal resistance of 0.0003ohm, and the Hobbywing EZRUN 0.0004ohm, surely there's not much between then at that level?

it depends on "YOU" and how competitive YOU ARE...

but a 17.5 does pull alot of power.. if Racing.
I run a Tekin 17.5 and a Tekin RS speed controller... in a RC10,SC5M .. as my signature shows.
