I've been using these Attys for months now, before many even knew what they where, not to be smart but I've been looking for the perfect drip tip for these, the glass I am talking about is absolutely perfect as it is very heat resilient and stronger than the derlin tips that are now made. There is a guy here on the ECF that has been making custom glass tips, these would be absolutely perfect for the LR306. I spoke to him once by way of PM and lost his name,handle, address, if anyone knows who I am speaking of please PM me with his name,
Thanks
