I don't see the Black Arrow SE as a 'better version' - just different. Some like the LE, some like the Smaug SE, and now people can buy this SE version if they prefer it over the LE version. The Smaug SE won't be made anymore except to fill older orders, so the Black Arrow SE is the option now for new buyers (unless you find a distrib that still has a Smaug SE or a used Smaug SE)
