1- do you guy' feel the tails are a lot softer/flexier than before?
2- would they benefit from some reinforcement? either added laminate or a stiffener bar between the tips?
Mine and my mates didn't feel any softer, we both followed each other to watch the rear end to see if it was flexing more and we both couldn't see any difference. I also have go-pro footage of just the board working and you can't see any extra flex.
