Great, I used to ride flex tails and flexible boards made by Louis Greco in Point Loma. Flexboards are the best. I rode flextails and flex boards and shells. Made by Louis and Stanley Plescunas. Flexible boards are phenomenal. They are like fish bend and flow like fish. Thus they have high speed by flowing with the water without cavitation causing slowing of flow.
The main advantage is that through a hard turn the tail will flex and increase the rocker to increase manoeuvrability and return to normal when in a straight line so as not to slow the board down... aside from that they look seriously magic i reckon haha!
There are quite a few reasons why i use suncure including the ease of use, the rapid cure on demand, long working times & less yellowing over time. Having said that it doesnt work with opaque pigments (you can use it but MEKP must be added for full depth cure) and i do add a small amount of MEKP to almost all mixes to ensure a propper cure throughout👍🏼
