As everybody on the lists know, I don't like stuporwings. I have done 
dozens of posts outlining in excruciating detail the drawbacks of these 
things and others have done dozens of posts supporting my opinion. But I 
have been getting hate mail from those stuck with these POS, they can't 
sell them or even give them away now, thanks to me.

So I have revised my position. Vinney, stuporwings are the best, please 
purchase your stuporwings from the poor slobs trying to sell them on this 
and the cavers list. And I also recommend, seeing how you are a firm 
believer in backups, that you purchase 2 pair.That way you will have 4 
bladders all together, which, as you already know, is twice as good as 
two.

I propose, however, that you do not write your name with indelible ink on 
your wings because these units have had so many owners, some are starting 
to look like a innercity subway wall and are a real eyesore.
