I am also a tropical warm water diver and mainly dive around SE Asia.
18lb is sufficient and there is absolutely no need to get a SS plate for the dive that the OP described. However, water can get pretty "cold", seasonal, in some places in SE Asia. I have seen divers using dry suit in Philippines.
A slightly bigger wing won't hurt. Aluminium plate is all required.
So it is no longer US$399.00 for International FREE shipping by DGX. Pity.
