Update...
Ok, figured, its been a while... I'd throw a quick update together... as I am really pleased with my current results on protecting the tip.
Ok, I had tried the dip into the rubber stuff... and it worked pretty good for me, for a while... so, then I tried the Bed liner, and it worked a bit longer, and pretty good again, for a while... BUT... this has worked now for months and months, I am really happy with it... its similar to what Jeff suggested, but instead of the plastic ... I bought the rubber ones, cut a small slot, and fitted it to the end of the PP... went on tight, has been on for months and months, and is still not showing any signs of wear... and don't feel I lost any sensitivity... I went with rubber instead of plastic as I did not want to glue it on... if you try this, buy the size that you will need to press on - tightly... no sign of it loosening etc... its on nice... and really, no wear, unreal.... here are some photos... please excuse the dirty PP... did not clean it yet from last nights hunt. But all in all, some great suggestions... but for me... this one did the trick, I bought a pack of 4... and may not even need the others, lol. Really has staying powers in this hard AZ dirt.
Anyways, hope it helps someone and thanks folks, as always.
