going to post a little premature since i my self just got my 7" lazer yesterday and will use it friday but i bought the 7 over the 6 out of complete curiousity my friends have a 6" and so i figured a 7 would be nice to try just a little bigger and my logic is (and I havent tested it yet) that when you are out in the extreme cold and your holes are constantly freezing up this gives you and extra inch to not have to worry so much about chizzilin out and the extra inch for when you have that big one no need to drill another hole.
thanks for the input....keep it comin! plan on upgrading possibly after payday tomorrow night before heading out friday morning. my mora isn't cutting worth a '#@* anymore even with new blades. and i don't think my carpal tunnel is making it any more enjoyable.
