What snorkle? Oh, you mean that snorkle.
I've been wearing a snorkle since before I started SCUBA diving so I don't even notice it. With the right head twitch I can have it in my mouth. As for it causing issues, I can make quite a list of all my gear I've snagged on one thing or another over the years but the snorkle dosen't come up. It is pushed back out of the way and lets the kelp, rope, fishing line, and so on go by and grab something else further down the line if it really has to screw up my day.
When I went back to a backpack, I tried (am trying) the long hose and found, at first, the snorkle was an issue. After dealing with it for a bit, again it became a non issue when I found the right technique.
I just ordered some bits and peices to try a different hose setup. I'll probably go back to the old school bungied primary, and may be a long hose backup, but I know I'll still have my 30+ year old snorkle attached to the mask with two snorkle keepers.
