Composite Wood Deck Expirences

I am in the process of laying composite wood deck over aluminum frames. The decking itself is structural so I found a residential decking material (Timber Tek) that was rated to span 24" centers. My expirence has proven this material to have good slip resistant properties when wet. As there is no sub-deck and the material is tongue and groove with weep holes I am cauking the joints with silicon. Small leaks are acceptable as a weather deck it only covers mechanical spaces. I doubt that I am the first to try this material and hope to get comments on it's use.
