Lib Tech makes good boards, no doubt. I think they're a little overhyped and overpriced, but they're certainly good boards.
If I'm not mistaken, that board should be traditional camber. I'm definitely not certain about that. If you're looking for a softer, more freestyle oriented traditional cambered board to compliment your Crew, it would fit the bill very well.
The price definitely looks good. Almost too good. If everything is in good shape, I'd jump on it anyway even if I didn't want the board. Hell, I'd keep those Forces and resale the board for the darn near if not the same amount as what I paid for the whole setup. End result - free Union Forces!
