100/75 here. Glide is better, but I'm not totally used to the edge. I may have a bit of an alignment problem with one of my holders (8090 - Lightspeed1) which would lessen the impact of the edge due to the flat bottom. I guess I'm a player that likes skates really sharp. Used to always get my skates done at one of the "best" places in town, Done Right. They used dupliskate sharpeners after a radius job. I've only done mine twice and the second time was much better. Jr.
