i too have had the same problem and probably like most i have ripped my hood around the poppers trying to put it on when cold...
I think i've solved the problem though.
Buy a hard top!
More secure and warm in the winter (no leaks) and in the summer just remove it. I can't remember the last time i had the hood up on my car.
Ok they are not cheap and some look right nasty, but it's worth a thought and keeping an eye out for a hard top.
The security aspect alone of having a hard top is great peace of mind. Before anyone could have broken in to the car simply by undoing the poppers and opening the door (had my tax disc stolen this way once).
So hard tops are the future!
Assuming your agile enough to remove it by yourself and have somewhere to store it of course.
Steve.
