Thanks for the comments regarding the 440v2, sounds good. I think I'll definitely give them a go.
A per the 600, yeah, they're a great shoe as well, actually one of my favorites. The downside with them is just that somehow it just didn't feel like they last as long as some other models -- my first white/green pair went kinda limp on me fairly quickly. Initially they felt AMAZING, but that didn't last as long as I've hoped. It could've been the skating and the frequency of it at the time, but still. Got another pair of them on ice, so yeah, will give them another go for sure.
I've sometimes thought about trying out the 808 or the 1010, but based on my experience with the 480, I think it's better to give them a pass, taking into account the spectrum of boardfeel I feel comfortable in.
Anyway, it's pretty much cupsole or nothing for me. I might go crazy someday and try the 306 as they look effin' great, but in general I don't feel like going down the vulc rabbit hole with my old-ass feet.
