These two boards are popular rocker/camber mixed boards in recent years, which can be eaten both inside and outside the road. Of course, Armada's style is mainly off the road, so the waist is very thick. It's interesting to compare. TST is not as energetic as JJ of the same length. From the plate type, the difference is mainly in the distribution of rocker and camber. TST is about 40% of head swing-60% of waist bend, JJ is 25% of head swing-50% of waist bend and 50%- 25% of tail swing. It seems that TST strengthens the performance of carving in the lane (relatively speaking), while JJ tends to be multi-purpose. Armada's greatness lies in making such a fat plate with a small radius of gyration (five-dimensional lateral cutting? ), indicating that the board is also very powerful on the snowy road. PS: If you buy TST, Armada will donate part of the profits to Travis Steeger (this is also the origin of TST's name), an extreme skier who died in a traffic accident in 2009.
