That was the plan. I actually think 3 pairs will be sufficient. My plan was to get these for the new R1s. I honestly don't need them, as I converted a pair of 1Ss to Sprungs for concrete rinks, but they are more fragile than I expected. I'm thinking about just swapping them for the R1 frames and keeping the second set of Sprungs for when my other set on my 2S Pros go.
(The other option is to keep both sets of Supremes with Sprungs for indoor and just wait till one pair is done before using the other. Then I would get the TF7s or 9s and use the R1s on those for outdoor. Not sure if it's worth it though, plus I don't really have space for another set of skates. I know myself and if I could just go try them on and walk out with them I probably would do it, but to order online and hope to get the right size, even if I can still return them, is not really that appealing to me. Then there's the added question of whether or not it is wise to drill a third set of holes in the 1Ss, or if that will affect the outsole durability and strength. My assumption is that it's fine, but I'm not sure).
