New setup! have some questions

Well after 7 years I decided it was time to refresh my setup old Hyperlite setup, so I got this new Ronix One board/binding combo shipped to my place in Argentina.

After making my expensive way through customs, I finally have the setup home waiting for it's first ride, I have many questions, hope someone jumps in and help.

I've been wondering how's this about distributing the weight on a 3 stage rocker (I come from a continous rocker), and how this variable rail thing work. Overall how do you ride this thing?

About the bindings I'm not sure I undertand how the laces work, I can adjust them but do they stay like that or loosen during the set?
Also, any home-made ideas to do the moldable thing? with a hair dryer maybe? I think I'll be adding the J-bars too. I tried the bindings and my heel had some play.

How's durability and warranty on this things?, I see it's all made in Taiwan now??? When my friend had a problem with the inserts on his Hyperlite board they warrantied it right away, should I expect the same with this company?

Really appreciate any input

thanks
Luciano
