as far as the baseplate dragging thing
i have not really noticed it as an issue at all for me. I seem to apply the same amount of wax as i always did. i am also riding a lot skinnier wheels though, so that may also be contributing to the ease of slide
i feel like my noseslides actually have gotten way better, it could just be a technique thing, i feel like i am putting my foot in a more ideal place maybe. but i feel like my noseslides and crooks are looking mint since i got these and i can combo so easily.
