Michael,
The spring idea seems fabulous except its a little risky aint it? Im a
little scared about that operation especially about finding a spring and
positioning it efficiently enough. Any ideas to make my surgical career
idiot proof would be welcome. If you have any luck with it do let me know.
Thanks,
Adi
