The reason i recommended Scotts was more for your crew. We hand out Scotts to the crew and then i draw on the chart our trip plan for them to keep. TTOL is always my best source for info

IMHO Cooper is overrated due to BB hassle and bad service but we go frequently so easy to skip for us.

another recommendation is to get swim noodles at base camp for snorkeling as much for visibility as buoyancy.
