I am always looking for wider fixed blade heads of high quality steel. One of the challenges in making a head like that is that if they are truly top tier tool steel, and they are machined from a singe chunk of steel, the cylinder of steel they have to start out with is REALLY expensive.
Bishop makes a 500 gr one called the BloodFloodz--it is a BEAST--1.5" cutting diameter 3 blade. Its on my YouTube Channel.
SIK just released the F4 and I just did a vid review on it (Lusk Archery Adventures), it is just like a Solid Legend, but is 1.35" cutting diameter.
The Solid Legend 125 grain is 1 3/8" with a 3/4" bleeder. That is really nice size for a fixed blade. Again, they can do it cause its not machined from a single piece of steel.
I also just tested the Tooth of the Arrow XL. It is a true 4 blade design that is 1 3/16. It is a solid chunk of high carbon steel and made an incredible hole in a steel plate. It held together about as well as any head I've tested.
