Really strong core in the Forges, they tend to read pretty darn early, and if you drill them even moderately strong and pin up they flare an absolute ton.
The OG Forge for me is extremely strong, works best on high volumes with closed angles, if I could ever catch a deal on a new one i'd probably do a weaker layout on one and see if I could shape it down lane a little more.
The Fire lane shines fast, and for some it gets squirty when this happens. Strong core, so again, careful on layout, it flares a ton. I have a Fire drilled weaker than my OG Forge and it runs circles around it in boards crossed, and I can really open a lane up with it. I'm a rev dominant player, but the Fire is really continuous and really good for me on heavier volume house patterns.
