I've flat landed the 2007 board way harder than the '06 I broke. Several times now with no issue/ no breakage ! The tips have been re-inforced with carbon to liven up the pop/response. The center of the board is also slightly stiffer to give a little more strength. There was a few bad boards last year that were broken. Those issues were corrected in mid 2006-2007 production. Breakage shouldn't be a problem for 2007.
You and I both know that these boards are hard to match as far as performance. With the low weight, great flex, and thinner core, these boards are great all around. All boards are breakable if you try hard enough. At least you've seen our track record as far as standing behind what we put on the water !
To sum it up, it will be much more difficult to break the 2007 Protoy. If you do let us know and you'll be taken care of !
