You think a light skateboard makes you pop and flip better, just like you feel more secure wearing safety gear. So, if you believe lighter vehicles would improve your performance, go for it. I wouldn't be concerned about durability if you're new to skating. There are lots of other things that can happen to light boards that won't happen to heavy ones. Lighter is usually better when it comes to skateboards because they tend to be more flexible and have less weight per square inch which allows them to handle well and jump higher. However, there are also many heavier boards on the market today too, so don't let this fool you! Any board will work for learning tricks if you practice enough. It's only after you develop your skills and become comfortable with the board type that you should start looking at different brands or sizes of wheels or trucks. The most important thing is to find something you love doing and enjoy watching others do it. If you're still unsure, try out a few practices on lower-quality skates first before investing in a good one. You might just find a new hobby!
