I found a great deal on a pair of Blazes and LT brackets, and couldn't resist taking the plunge. I had demoed a pair of Sparks and figured the change was inevitable. I replaced a twelve year-old pair of Sims Master Link aluminum-base bindings on the Voile hardware I'd been using.
Just in holding a Blaze in one hand and a Sims with the track in the other, I was a bit astonished, and reckoned the difference was about a full pound. I was damned close - I went to the grocery and availed myself of a digital scale: Blaze = 1.73# and Sims/Voile = 2.65#. With the swap to the LT, I indeed saved at least a pound per foot.
After I mounted everything on, the board felt absolutely featherweight in comparison.
Can't wait to get out and check it out. Thanks to Will and Jeff at Spark R&D!
just did the same and got out for my first day on them yesterday. Noticeably lighter, for sure. The forward lean adjust is nice as well--zero forward lean for climbing that is--but kept forgetting to adjust upon transition. ha.
