If you want to try it when life is marginal, and lets face it this is when it usually matters, then try setting full flap on a C152 with max TO weight.

But remember to pick a runway that you cant see the end of, preferably as a result of the curvature of the earth.

Good luck, and hope the ground effect is higher than the fence at the end.
That`s silly!!

You should not go around or take off with flaps full.

Once upon a time - a B17 pilot from the second world war - took off from a grass strip in a C172. Two fatties and me a skinny and a large heavy suitcase.
He said he would do the take-off (as he had flown B17s full of heavy payloads and stuff and he owned a C172 in the States and was current it sounded like a good cross section of experience to me)
So he took my original flap setting 10. lowered some more, by inspection, and proceeded with the takeoff. The aircraft lifted off with best perf.
I was left to clean up and accelerate - no problem.
Point? Use the flaps for the perf required.
(Best takeoff I`ve seen at any weight)
