All air equivalents of fibreglass are more stable, plus you have the added bonus of there is no chance of having a beam split in the way a fibreglass pole would. Where fibreglass will flex only so far before failing, beams flex and simply pop back out. The key is really getting a mixture of pegs for different pitch types I.e good plastics, rock pegs etc. As with pretty much all brands the supplied pegs are pretty poor.
We have just purchased the Invadair 600 and are currently in the south of France, as anyone that knows the area, it gets quite windy for long periods. The tent has proved itself under these conditions with gusts in excess of 40mph it never faultered. It was a little unfortunate that we had a torrential downpour which lasted a complete day and coupled with the wind a poled tent would have faultered. However, this tent was bone dry. As for the air beam system we suffered two explosions on the same beam. Sunncamp sent a new bladder out but that went bang as well. It was down to a sharp piece of plastic in the sleeve. Mind you when they go they go. It woke the site up and did not do much for my nerves. This has not put me of the tent. It is a brilliant piece of equipment and good value for money.
Reviving a 3 year old post, would be interested in knowing how this tent has done over the years, was it an invadair 600 Pro, or standard invadair 600.
I quite fancy a 600 pro
