Keep using the BK deck until you can buy a more proper one. Pick up a series 7 tech deck and use the trucks with the BK deck. Upgrade the tuning with teak bubbles or o-rings (or try the combo of both) and maybe get the teak wheels if the BK wheels haven’t already shit out on you. I’m suggesting these options because they are all available on amazon. Hope this helps!
