Goggle Strap Under Or Over

I train as I would race: straps under cap. 

I think it helps to get the real feel of the swim with the cap on (overheating or too cold). also, if you have a dock start, with the straps under they'll less likely shift on entry.

I've have numerous times where I've had my goggles kicked off and the cap held them closeby.

I don't train with a swim cap unless swimming in open water.  However, I am used to caps as I swam on a swim team when I was younger.  It's worth wearing it a few times just to get used to the feeling/sound difference if you haven't worn them much before.

I prefer straps over the cap.  My goggles go on last thing before the start so they don't fog up from standing around.  When they're under the cap the only thing you can do is lift them slightly onto your forehead.

It is preference, for sure. 

I prefer over because it's hard for me to get my goggles seated properly pre-race. I'll likely have them on and off a couple times, and then again once I get in the water(if they're leaking). I don't want to have to deal with taking off the swim cap, adjusting goggles, then putting the swim cap back on. Especially for a water start. 

And when I have been kicked, I've been thankful that I don't have to deal with re-positioning the goggles with the straps trapped under the cap. Can't imagine trying to sort all that out during a swim. I'd rather swim without goggles. No biggie. 

ETA: Does Tony prefer both over AND under?

The only time I did get really kicked in the face, strap-under-cap made it worse.  Never again!

Details: In my races I always did strap-under-cap so if I got kicked they wouldn't come off.  Nothing bad ever happened to my goggles until IMLP 2010, when I did get kicked in the face only a few minutes into the race and the goggles went sideways a bit and started leaking water. The first try at fixing this they still leaked, the second try they still leaked, the third try I realized the straps were messed up.  I tried to fix this all while treading water and my heart rate was shooting up and a kayaker felt I was in distress.  I ended up hanging off a kayak for 5 minutes fixing the mess (removing the cap, fixing the goggles, puttnig cap back on) and then hanging there getting my heart rate back to normal. 

At IMCDA last year I did strap over cap and while I was a little worried the goggles would get kicked off entirely and sink to the bottom, at least they were easy to reposition.

I'd love some tether-type solution or better yet floating straps or something, to not worry about the lost-my-goggles-now-what problem.  I've seen a few people have a 2nd set of goggles around their necks, seems like a hassle to me.

I don't use a cap when training. When racing, either in swim meets or open water events (swims or tris) I wear the straps over the cap. I have tried them under the cap a few times and it does not feel as comfortable.

BTW, that being said, I find it funny that my BT picture is from one of the few occasions in which I wore the strap under
