Dragon's most current Firefly IC Hybrid does not have magic tracks but has DS Tracks. They are pretty nice. I suspect the Tasca IC will have the track section in 2 pieces as is their norm for these types of tracks.
I agree the Tasca kits are better for fit and can be more accurate in some of the options they offer i.e. their current Firefly VC's versus DML's VC Fireflys.
