lehner 2400XL/warrior 7018/18cells?

[maxxdude1234]

hi,
I'm looking for an 18cell brushless set-up in my maxx. Before anyone suggests going for a smaller cell count....don't, cos I've already got custom made 18cell packs.
Do you think a 2400XL or a 2000XL would be the best option, bearing in mind I want to use the 7018. The 2400XL has a current rating of 60A, and the 2000XL 55A. Would the 2400XL have heat issues?
Many thanks...
