I dive almost exclusively in Cozumel, just drifting along enjoying the scenery. I rarely have to do any fast finning, unless I need to stay on something for a quick photo. Are my Twin Jets going to be GTG in Thailand on a LAB, or is the current such that I may need a blade fin? I'll be doing 4 dives a day, so don't want my aging knees to have to sacrifice too much. Thanks.
