When I got back into skateboarding a year ago after after a 25 year break I did the mistake of getting a complete because it was easier. Same story, my kids wanted me to come along to the skatepark.
The complete was a pretty decent Almost deck with some Tensor trucks. Far better than some of the shitty trucks you find on some completes. Problem was that the deck and trucks were too small at 7.75 and the wheels too soft. I upgraded two weeks later with a wider 8,5 board, Thunder 151 trucks and Bones underneath. Now I’m on Ace 44, 8.75 deck and riding a couple times a week and active in the local DIY scene. My kids don’t skate anymore, though.
Maybe I wasted 100 euros on that complete, but it got me back to skateboarding and was way more fun than no board at all.
