Thread: To hook, or not to hook...

My EM-332 stock is coming along nicely. All sanded down and grip resized/reshaped to provide a fantastic hold. My question is whether I should cut a small hook in the heel of the stock, as per the grey patch in the photo below. It is more common on sporters, target and tactical rifles and I don't want to munt the stock. Any thoughts on whether / why I should or shouldn't? Suggestions as to shape, size etc also appreciated.

Before anyone tells me I'm ruining the resale, the barrel has been developed and the original iron sights are long gone, so that isn't too much of a concern. I also have no intention of selling it!
Thanks!
