Clip-on mic position?

I've been experimenting with my clip-on mic lately, trying to position it at different spots around the bell and at different distances from the bell. I know that many folks put it at the bottom of the bell, but I find that when I put it there I run it into things no matter how careful I am

So, I'm curious what others have found successful. I'm using an AMT Wi-5, usually on my Mark VI tenor but sometimes on my 10M and Yamaha 52.

BTW - pictures would be great!

Thanks.
