I guess that's the difference between racing and touring Henry - I have two of Stuart's engines and in 40-odd years of sporting road use I've never had a centre main bearing fail - replaced the shells twice but only as routine maintenance. This with over-bored A7 pump.
The problem now is finding a good shaft to start from - most are by now well-used and down an undersize or two. Although new A7 3-bearing cranks are available in Australia.
