I'm no expert, but I've played with some suspension options and really like what I have now. I really value simplicty both in terms of being light and simple to set up: 4' poly tree straps, 6' Whoopies made from 7/64" Amsteel, Dutch Clips on the tree straps, and Dutch biners to connect the whoopies to the tree straps. Just wrap the tree straps around the trees and clip on to them. Pull the whoopies to where I want them and I'm done. Maybe a minute or two.
I considered the dynaglide whoopies, but I don't see the benefit. I read on HF that people were saving 3, 4 or more oz vs amsteel whoopies, but mine are less than 1.5 oz for the pair and I don't have to worry about pushing any load limits, so I'm sticking with them. Those folks saving oz's must have had some heavy, longer, and thicker whoopies originally. If you are just starting though, go with what you have. I can't comment on making dynaglide whoopies--seems like I'd go cross-eyed trying to work with 1.8 mm line!
If you have a hammock that has a "head" and "foot" end, it's a good idea to use 2 different color whoopies so you can tell them apart while setting up. On a regular hammock it shouldn't matter unless you just don't want your head where your feet have been!
I think the structural ridgeline is really useful. It makes sure you set the sag correctly every time and it distributes some of the forces. Your dynaglide would be perfect and you can make it fixed or adjustable.
Hope this helps and I'm curious what other folks are using.
