I usually plan my ToL use so that I get the highest number of uses in a fight during phases of intense healing. I decide whether I want to boost my Tranq with it or use it separately and also whether to use HotW or NV with it (and possibly use ToL + HotW + Tranq for some ridiculously powerful healing - or spread them out for more CD coverage).
The exact timing for Tranq, however, is determined by the raid as a whole. We assign most healing cooldowns to the phases of major damage. If we have more big CDs than phases of high damage we leave one or two unassigned as screw-up recovery. Monks are perfect for this because theirs is an instant cast, Druids with Tranq are the first ones to be assigned since the channel time has to be planned anyway. So my Tranq is never unassigned and I plan my ToL / HotW usage around that.
Long story short: Pretty much every CD use is planned before the pull, saving a CD or forgetting to use one never really happens. At least not in the healing comp we are running.
