I always teach my students to give an airplane full power on take offs and go arounds.....I want it imbedded in their minds that it is better to have the power and not need it, than to need the power and not have it...you can always reduce power after you have analized the situation.....so why am I telling you this...because what you are learning now will become habit tomorrow...if you get in the habit of not giving full power on takeoffs and go arounds...one day it will cost you an airplane....
now with that said..you can probably get by with the 32.....once you have a positive rate of climb reduce power....
