Well my only question is, if you are so sure your one finger technique is right for you, why are you even questioning it? I personally don’t care either way how you play your music, it’s your music. I very much doubt any harpist will agree with you and say “oh that’s a great technique and no you’ll never have a moments trouble with it”.
By playing with only one finger you are limiting the music you can play. Because there is a great deal of music that does actually use two or more notes in the melody hand at the same time. You are also missing out on being able to play rolled chords with both hands which is a recognisable “harp” sound.
I won’t tell you to learn proper technique out of any elitist attitude as I am also not a classical player. I am encouraging it purely from the point of view that you will have more versatility in whatever style of music you play. There will come a point where finger pecking as you call it, won’t be able to keep pace with the music.
You might be interested to know that there’s not a harpist on the planet who thought the traditional four finger techniques were natural and easy the first time they did them. Like anything it takes time to develop it. There are hobby woodworkers who never take the time to learn how to use tools properly. They have fun with wood but don’t turn out the most satisfying work. I think the same can be said for all hobby’s. Just because you don’t earn an income from it doesn’t mean you necessarily need to be unskilled with it.
