I got my first real twin (Opera twin slick 8.25x14), and as soon as it arrived in Turkey, I grabbed it. Although the reviews for this deck here and on YouTube are not very promising, I tried popping it at home and honestly, despite the steepness, it felt quite light due to the crispness of the board or the wheelbase.
Before this, I had bought two Mini Logos and gave them to my carpenter friend to convert them into twins. Despite the concave, this board feels lighter compared to them. The Mini Logo is the one on top in the photo.
I will master the kickflip with this board. Wish me luck.
