Steve,

In one sense, when you say, "So pick which ever you like best", you're perfectly correct. However, then you wrote that, "My choice, uplocking. Mainly just because there are more choices in hardware to pick from." Now that too is correct and therein lies the problem for those of us who want to build a rod and prefer the D.L. seat. There are simply very few choices available to us. Seats are almost exclusively designed for U.L. Not only that but manufactured rods are similarly almost exclusively U.L.
I don't think the lack of choice really effects our buying volume though.
