I will be visiting the machine shop tomorrow and we will go through the entire process with the manufacturer. He should get the prototypes made very soon though, I will update you guys sometime tomorrow.
The lighter the better. Heavy undersized throws suck. There isn’t a market for them. If its going to be small, the weight has to be small as well.
And make sure you put whatever weight there is in the right place.
I consider this more midsized. It’s in between the most popular oversized diameter (56mm) and the most common undersized diameter (50mm) making it IMO mid-sized.
