It seems as if costs have risen a lot over the last few years. I wouldn't be surprised if, knowing folks are already spending 200 for a 12 and 325 for an 18, they figure their path to profit is to sell an even more capable driver and charge more for it.
The issue is often selling enough of a "specialized" driver...we see the nice gent from SI mention this frequently in response to people asking why are you ending the XYZ driver? Or....why did TC go under? What happened to Chase/Chane etc....
If like the ultimaxes they can do sealed or ported well, I would think many here would willingly pay more for more capability....and Dayton has had an good track record (imo) of offering drivers for along period of time and supporting them well.
Dont be surprised if they discontinue the old HO and HF series...they are long past their prime time imo.
