Newport Gwent Dragons' colts enhanced their club's reputation as the bogey team for Scotland's professional sides when they won the Glasgow City Sevens at Dumbreck on Saturday. Sadly the main pyrotechnics on the day were produced by the weather as what had been a glorious afternoon was transformed by an electrical storm that meant the closing stages were played out in front of only a handful of spectators.

By then the full-time professionals had asserted themselves, defending champions Sale Sharks also reaching the semi-finals, where they went out to Warriors. That Glasgow then lost 14-12 to Dragons in the final was utterly typical since Dragons may have finished in their customary spot as the lowest-placed Welsh side in the Magners League this season, but in that competition they lost only once in four meetings with the Scottish teams, better than any of their compatriots.

Yet what was remarkable about that result was that it was the first defeat of any sort suffered by a Warriors team since March 21. While Glasgow's seven, comprising players on the fringe of the first-team squad and youngsters from their academy, were being beaten, Warriors' first team were rounding off what has been a magnificent end to their league campaign with a fifth successive victory.

That they out-battled Heineken Cup finalists Munster on their own turf underlined the progress made by the squad this season as they earned a top-five league finish for the first time.

Even more impressive was that Edinburgh finished above them after their victory at Llanelli, meaning both Scottish teams had won on the road for a second successive weekend. Edinburgh have also avoided defeat in Wales this season, having drawn at the Dragons and beaten both Ospreys and Cardiff Blues. Indeed, the only team to beat Edinburgh since March were Glasgow, who subsequently finished with three wins.

Clearly concentrating resources into two teams has reaped rewards after the controversial, but shrewd, decision to axe Border Reivers a year ago. The next challenge is to start building the profile of the teams which is why, in a strange way, events at Dumbreck had the potential to be more important to the Warriors than those at Cork's Musgrave Park.

Once again Cartha QP staged a fine event, attended by more than 1500, many of whom will not be among the regulars at Firhill.

A club that has been quite outstanding in both the way it has developed itself and rugby in its community, Cartha has commendable ambitions for its sevens tournament and is looking at ways of enhancing it.

What Saturday suggested was that instead of a single tournament held over two pitches, the way forward may be to stage two competitions running concurrently, with the professional teams in one and eight of the city's club sides in the other.

It is a remarkable fact that there are so few clubs within the City of Glasgow boundaries that almost all of them could be accommodated in such an event which could be jointly promoted with the Warriors as co-hosts.

The only downside to that might be to prevent them from inviting Scottish clubs from outside the city and that might be harsh given the respective contributions to Saturday's success.

While GHA, Cartha's nearest SHE Premiership neighbours, called off on the eve of the tournament, the "amateur" club that went furthest was Dundee HSFP. They may well have drawn their inspiration from the decision made, just days earlier by Ian Rankin, their head coach, to stay with them after their relegation from Premiership One this season, in spite of approaches from several other clubs.
