This is the closest I have been able to find, after looking at all the stick manufacturers that spring to mind.
Sadly they are not Oak :(
As for the custom sticks... I'm not 100% sure it would be worth it, they will likely be expensive and with a company name like customdrumstix I'm not certain the quality control would be fantastic... Maybe order a pair or two, try them out. If you like them buying them in bulk to keep the prices down will probably be the best option
