Ahmed,
The points I was making are;
1. A Nose clipped stage is inherently more likely to be lost than one clipped both top and bottom, regardless of your procedures.
2. You can quite happily carry more than one stage this way.
3. Whilst 80's may well be "best" a 7 is perfectly useable.
Thats all
Oh and I know of more than one case of people losing nose clipped/leashed stages, but none yet of double attached stages being lost......
