I need to start thinking about buying new blades and I found some Pattern 99s that are 1/4 inch bigger than the blades I have right now. The new blades are good deal if I were to buy them online, so I was considering changing the blade size I use. I went with an 8.75 blade before since that's what the skates came with when I first got them, but from what I can see Jackson skates in my size (4.5) could work with either 8 3/4 or 9 in blades. Does anyone else have experience going up/down in size for the same blades and if you do, did that work out? I will ask the pro shop where I normally go before I buy anything, but I just wanted to know if anyone else had already done something similar.
