All these different terms confuse me. I thought we had established
Tack and Duck tacks and the words to use.
Re what is better?
I dunno I've seen people do jump tacks (regular tacks or just tacks) really well, and there was no stopping the board, it went straight upwind, the rider gained ground.
Obviously one can be better than the other, but if you're really good at one, you are probably better off using that until you are great the other type.
For the duck tacks, if you are underpowered, loop the kite. The advantage of that is that you then also come out with no line twist...drawback it will pull deeper in the window and your upwindability might be a little off for a second...but I guess better than losing speed?
