yes
With a sprocket nose you must use a chain with the same chain pitch as the nose whereas with a roller you can use any pitch i.e. 3/8 or 404.
FWIW In the last 5 months I have had 3 CAT scans, an Ultrasound, a PET scan, 6 rounds of blood testing, visited the GP about a dozen times and seen 3 specialist (Kidney, Neurologist twice , Lung). The PET scan cost ~AUS$1500 and the CAT scans are ~AUS$550 each. I've paid for slightly less than half of two of the CAT scans, while the blood tests, and other scans were fully covered by compulsory medical Insurance. The specialist visits are about $350 and I get just under half back from insurance, The GP visits are $80 - $120 each and I get back ~ 1/3rd from insurance. During the same time I've also accrued about AUS$2000 worth of dental expenses which additional private medical insurance has reimbursed about half.
I have also now reached a medical expense threshold for the year whereby the government medical insurance will cover a bit more on GP and specialists visits and all my scans for the rest of the year are fully covered. I will probably have some hospital expenses in the next few months so with private MI I could use a private hospital (less waiting) but the public hospitals are just as good.
