I think like slowhike said, the advantage of the Speer is closing the ends. It also has more useable room on the ends. To me the disadvantage is 2 more tieouts.
I like the deeper Cat cut. Seeing the Warbonnet tarps, I think my next one is going to have a little deeper cat cut on the bottom, a small cat cut on the ridge line, and not be a true hex shape. I want to make the sides longer than the ends. That will make more usable room on the ends.
Is that too much to ask? Girls with frikkin' lasers on their heads?
