I emailed LibTech inquiring about the T.Rice and Darker series boards and this is the reply I got back:
"The T.RICE PRO is a solid board, and the 2014 looks great! The difference between the HP and non HP is all in the fiberglass. More specifically, the HP doesn’t have fiberglass! Instead, it uses a renewable basalt glass made of woven basalt. Not only does this mean that it uses a renewable resource, but it is also significantly lighter. The basalt also has a closer flex pattern to the wood core than fiberglass, but this isn’t as noticeable as the weight difference. They both have the C2 bottom contour, so you get all the pop of regular camber along with all the benefits of banana! As for the blunt vs pointy tip and tail, that’s pretty much for cosmetics only. We put the blunt tip on the smaller boards, and the pointy on the bigger ones. You really won’t know a difference in riding it, it’s just for looks. I highly recommend this board, and just built one myself the other day at the factory! Also, we are releasing a new size for this board in the next few weeks! There will soon be a 155cm, so keep that in mind if you’re thinking of a board around that size.
The DARK SERIES is a great board for the more aggressive rider. It’s a stiffer board that charges! It now has C3, which is closer to the feel of regular camber, but better because it’s a banana! I recommend this board to people who ride fast and hard, and need a board that can handle it. It has a far more aggressive edge hold than any of our other bottom contours, so it’s best suited for a strong snowboarder."
