Yeah, in theory it should be perfect (it was the first thing I tried when I got flash), and I'm not sure why for me at least (though I'm not the only person who finds this), it isn't, but I think it exaggerates flashes already "erratic" or at least oval movement patterns and makes it that much more awkward to control effectively.
Generally though, I just found I couldn't KO stuff as effectively with it.
Oh, also I don't like the 145 height for attack, because of the risk Low Track opponents present (not that MF-H Scythe Kronos 90RS won't reliably beat S130, but it's a very uncommon bey in most metagames, and the main users of Low Tracks nowadays are stamina types, so as long as you get metal-on-metal contact you're basically home).
By the way, if you're worried about asking me something that might not be on-topic, just shoot me a PM
