Im currently finishing my rescue course. I have been renting so that i could try different types of gear and then decide. I still have no idea. I think that i should just go with the most comfortable set up within my budget... is that the right direction? I like so far wither the Sherwood Avid, or the Seaquest Pro QD. Both jackets as i have never done a dive with a back inflate... one more thing, opinions on an octopus vs. a secondary attached to the inflator such as a Gemini? Thanks
