If you use algs to solve then you are relying on help anyway...
You didn't get it.
To a non-cuber, if you pull out a sheet of paper, and follow a set line of moves to solve a cube, they obviously aren't going to think you can do it on your own.
If you have all the moves memorized, and show it to them, they will be actually impressed, because you are just doing it, without following instructions on a sheet of paper.
In fact, even non-cubers who know that you use algs, they will sometimes still be impressed that you memorized so many, and know which ones to use, and do them fast.
Like I said, I just wouldn't go to a non-cuber, tell them I can solve it, then pull out a sheet filled with algorithms, as I follow it to solve the cube, and expect them to actually care or be impressed. And then facepalm when they aren't.
There is a huge undeniable difference to people, between solving a cube using algs from memory, and solving a cubes while looking at an alg sheet, as you solve.
In fact, I never considered my first solve a solve, when I used sheets. When I was able to do it purely from memory, using the Beginner's Method, is when I considered myself to be able to solve it. Especially in front of people.
