well, it will be more expensive to crash a MC28 and ding that swingarm. You can also fit a PGMIII and associated kit to a MC28, but then you're losing half the appeal if you do that.
I think the answer to the question is that both will be a reasonable starting point as long as you get it for a good price
When you make it to Vic and you are in Melbourne, send me a PM, happy to catch up and chew the fat about NSRs.
