I am building my first board, I am currently using a complete by Element.
So I've created a list of what I am going to do. I already have some of the parts and am planning to buy the rest by the end of this week. What do you guys think?
I just went back over previous posts to check and see where you were at, so as per others comments on here, I mostly agree with everything said so far.
Quite simply the harder bushings might be the main thing that would really help you, as both those Element completes and most stock bushings in any brand trucks are 90 duro, so although they all do firm up after a few sessions, they are all going to be fairly soft compared to what might be best on 92 or even 94 duro bushings for your size, balance, etc.
I have a lot of those Element boards for kids to ride at the indoor skatepark I am at and have tried all the parts on my own setups, as well as skated them just to see how well they hold up - better than I would have thought actually, but yes they are a beginner to basic intermediate complete, so although things will last perfectly well for starting out, they will only get you so far.
That said, buying a whole pro complete is not necessary, but I would not stop you from getting whatever you wanted in that regard, eg you have all the top brands listed there now, which is pretty much what I ride anyway, as do many others.
Lastly, just so you don't go down a rabbit hole about things, learning to stop, start, stand on the board and lean to heel or toe sides, pushing, rolling faster, and turning both with lifting up as well as just carving all takes time, so from what I had seen of your video, you are already well on your way, which is good to see. It really is just about putting in the time and getting comfortable on a skateboard, rolling around and building up muscles that might not otherwise get used a whole lot doing other things and taking care not to go too hard or try anything too quickly that could result in injury or other issues.
Whatever your board setup, it will not magically make you skate significantly better or worse, but it can help a whole lot having good quality gear you can get used to, hence more than anything, the harder bushings comment to start with.
Hope that helps anyway.
Good times ahead!
