I just checked out the lib-tech website, they rate the flex on all there boards from 1-10. 1 being the softest and 10 being the most stiff.
T-rice = 7
Dark Series = 7.5
TRS is a 6 for the 159cm and 7 for the 162cm
The T-rice is a midwide and the dark series is a wide. The trs is the least wide of the 3 boards and i am afraid it will be too narrow.
