The difference in cost for 1000ft spools is <$50 CAD, and you get a product you know always works, is less brittle, can do PoE without becoming a fireball, can be used in commercial installation legally, and is actually in spec. I mean a lot of people who are actually running cables already have separate spools for solid and stranded, plenum and riser, maybe even shielded/burial... no need to add CCA to the mix with all of its downsides (and potentially make that mistake...)
