Hey Gjenks & All,
Hmmmnnn, it appears that many divers have many opinions, and we are ALL sure that ours is the best. Of course all of you guys (and gals) who think you know everything really annoy the crap out of us who really do...(big grin). I guess my point is, go with what YOU like and feel is appropriate. My Tusa Duo-Air not only gives me easy breathing air and one less hose to worry about, but the high volume of air that it can direct to my BC can be a god send when I realise that I didn't judge that bottom just right. I have over a hundred dives with my Duo-Air and would not want to dive with a plain octo. YOU have to do what you feel is right for you. Sure, listen to the advice, but remember YOU have to live with the decision you make. I have seen those with the integrated octos spurn them all of a sudden and I have seen the converse as well. As divers we are passionate about our equipment, and some times we don't allow for variances among our friends. So have fun, dive often and use the equipment YOU want to use...
