To whom it may concern at Wetiz, 
I am looking for a race board, but I am not able to tell the difference between the following boards. Maybe you can help me.
HERO board (https://wetiz.eu/en/semi-construction/1308-131675-board-semi-construction.html#/85-colour-white).
FREE board (https://wetiz.eu/en/semi-construction/1197-131663-trackster-pro-carbon.html#/85-colour-white)
BIG KILLA board (https://wetiz.eu/en/semi-construction/1307-big-killa-board-semi-construction-70-85-kg.html)

Thank you for your help.
