Heading to Key Largo for three tec lite dives (up to 1 hr running time) this weekend on Duane and Spiegel Grove. I am debating if i shall bother to pack my drysuit/undergarments or my full 3 mil will do the work. I am probably average in handling temps; this will be my first time for tec dives at the keys this time of the year, not sure how cold it is compared to other years. Any advice? Thanks!
