Should I...

upgrade my coil to this:http://cgi.ebay.co.uk/AUSTIN-ROVER-...yZ43122QQssPageNameZWDVWQQrdZ1QQcmdZViewItem?

Would it give me a better spark?

pointless mate the current coil does the job fine it'll be a waste of money TBH if you want a good spark just make sure all the ignition components are in good order.

Ok then, was just trying to save paying out for new leads and plugs lol.

As Ed pointed out before, the maximum spark a coil produces is limited by the ignition components (earth, positive wire, coil lead, distributor, plug leads and spark plugs).
