I agree with Scott. If it ain't broke, don't fix it. I am not aware of any of our old antique shaft logs causing a catastrophic event. I'm sure that there are stories of failure but they must be so rare that it makes me wonder what the allure of the "new" dripless is. Goretex in the original units works fine with hardly any drip at all. Better to spend the money on something that will really be an improvement.
