Anyone have experience using stainless steel taps for tubing? I see over on the SmokyLake site that they offer these in 50 packs for (presumably) 5/16" drops. I'm a small operation without plans to ever exceed a couple hundred taps on the line, I inherently like the idea of making the investment up front and then using material year to year...do they face any of the risks of increased microbial activity, though?

Just looking for any hands-on experience, I'm also considering the check-valve style for next year.
