Ya the numbering system is strange for the 0.5.
Quad 0: 6-9-11-13
Quad 1: 6-9-12-15
Quad 2: 7-10-13-16
Quad 0.5: 8-10-12-14
So given my stats 9.5 size, 280 blade, 220 pounds Quad 1 is suggested, not sure what 0.5 is suggested for... Skate on a 11' (use to be 13' back in the day) trying to work my way down in number but not to the point of falling(9' is to small for me) so the 0.5 looked perfect to me.
Great post. Thank you.
