Hey,
You guys using CA hinges, how are they from the binding aspect? I guess I never installed them right or gave them enough of a chance. All the ones I ever used never gave me enough throw and seemed way to stiff.
I am with Steve and prefer the dubro large scale hinges with one pin the entire length. I just finished a 540 and used robart pin hinges for the first time. Lining up the pivot points is difficult and I'm not really happy with the installation. I am much happier with the dubro solution. However, it does take about 4 times longer to do.
