So, some Dove fans here, some less than fans
Dove heads are nice if they don't leak, but people have seens some bad castings here and there. I don't want to pick a camp, some are passionate, but if that head is a good head, it's likely good for your Snake, same with a tunnel wedge
As far as alum CJ heads, someone will likely chime in, but I think he makes something he calls a Canadian CJ, not just a simple copy of the CJ. They flow real well, 300+ well.
