I have been skating since 86, and it took me until probably like 91 or 92 until I started landing tre flips, but I have never had them really consistently until the past couple years. So, it took me nearly 20 years to get them on lock! I think that I messed myself up by learning Impossibles first, then nearly every time I tried a tre flip I’d do an impossible. I had to finally stop doing impossibles to get the tres on lock. I think that it is a lot easier to learn tre flips by doing them off stuff, like a little 3 set or a curb or something, so that your board has more time to flip and spin. I could do them off things before I learned them well on flat ground.
