I've been trying to compare some kits. BoyGoFast says they have bearings instead of bushings. Powerkingshop says they have bushings instead of bearings. Yet, from what I read, Powerkingshop gets better reviews. This may be wrong because there are not a whole lot of reviews. So whats you're opinion on whether bearings VS bushings makes or breaks a choice in kits? I kinda want to go with BoyGoFast because of the bearings but I want to go with Powerkingshop because of the satisfied costomers.
