After doing some more reading, it seems the Helix on occasion in some cars requires trimming and I would guess the Wagner too since they are so similar.
The VRSF 7" claims to not require trimming but I just don't see how its physically possible. Those 2 inches have got to go somewhere...
I think this means that for a true bolt-on I'm stuck with Forge and ETS 5". Otherwise if I allow for the possibility of trimming then all other kinds of FMICs enter the picture, for example the ER Competition one (right now there are a lot of deals, this one can be had at $750, which is even less than the Forge).
