I have had recent experience with both 875 and 1500 - the 875's came as a youth model (size 3.5) and were too small. I did skate on them for about a month. Aside from the low heel and three hooks instead of four (youth model design) and the length being too short, they did seem light and responsive, and generally comfortable - except when I skated (not the correct size). I purchased the 1500's thinking they would be more like my previous pair, 900's, no longer made. The 900's were awesome and amazing. Well, the 1500's are very stiff. very. maybe too much for my level of skating. (no axel, adult). I have been on them for two months and they are uncomfortable. I get ok forward bend for sit spins, but laterally they are stiff. I may ending up buying yet a third pair. much $$, but they need to work in order to be able to skate. I would consider the 875, as the 1500's are heavy and very stiff, my opinion. My friend (high silver adult w/ big axel) has the 875 and likes them. best of luck in your selection.
