I have a DD XV on the way.

I'd like LIGHT and ergonomic.

I think the thin and round rail system by Troy is very cool, but i guess that it is a tad tough to mount stuff. I will not mount a BUNCh of stuff on it. MAYBE a light. MAYBE a laser. I do like the option of a continuous rail for more flexibility in mounting Optics.

But... I'm also looking at a DD EZ rail - they are reasonable and easy for the avg person to install, but offer a continuous profile.

How is the Troy equivalent? - about the same price.

And... how are these compared to having a Magpul setup. Magpul is ergonomic as heck.

But, in general here are some questions:

1. What are advantages and disadvantages to free float?

2. How do the above handle heat?

3. How do they compare on weight?

Anyone CHANGE from the above for good reason - experience?

Thanks.
