lots of great insite and seems the most used is the groundhog.
we found Y alum ones at walmart that are 9" and i forget the weight but I did the math and if cut off to Hog length would be about same weight.
my son has 8 of those for his new HH Monsoon fly. am tring to teach him that they dont have to be all 9" in the ground. He came back from camping with friends and had a couple bent and twisted up but still usable.
I'm thinking of getting the same ones and cutting them off to about 6.5 to 7 in. and going that way, only $2 for 4 of them.
