Which plugin to use to create subsites which replicate the main site theme and menus

I need to replicate the look and feel (theme) of my main site - mysite.com - on my subdomain sites within my multisite install, with the same menus and footer detail. I am not sure if Cloner is the right plugin for achieving this. Each subsite will have its own functionality - like webinars.mysite.com.

Or will I achieve this with the - New Blog Templates - plugin?
