about not having a trustworthy buddy, I would agree that diving solo would be better then diving with someone that is going to be likely to be cause more problems then they could solve. I guess I kinda take it for granted that I have a dive buddy that I do all my diving with and know I can really on, if that wasn't the case (like if I ever had the money to go on a trip) I can see how being by yourself could even be safer then diving with someone dangerous. That being said I still feel that anyone that doesn't have I good dive buddy should be looking for one rather then just thinking the can get by by them selves, maybe you can do 3000 dives by yourself and never have a problem, but if you do someday have something go wrong that you can't take care of by yourself it is sure nice to know that there is someone down there looking out for you.
One last thing, I did not mean to offend anyone with my previous comment about strokes, nor do I mean to offend anyone with this post, I am just expressing my opinion and hope we can discuss the issue with me accidentally pissing anyone of.
