I had a WC Hoolie etc until a pole broke 3 days into a week's cycle tour for no obvious outside force. The tension in the pitch was possibly the only stress on the pole but it had a design defect in a three pinch hole fixing of the pegs on the end of each pole segment, this fractured suddenly. It had 9mm superflex poles I think.
In my case the poles could be replaced with equivalent aftermarket DAC or Easton pole segments due to them being straightish poles. Unfortunately the pole failure put holes into the pole sleeve. We got away with a pole tube repair for the rest of the trip but it went back.
In your tent there's a prebent shape to the poles. I doubt you can get those replaced with better brand of poles. If you can get DAC or Easton poles to suit then I'd suggest that's a good idea to consider. I'm not a fan of WC tent poles, simply don't trust the brand. I fact I'd check every pole segment before each use to see if they have those crimp pin fixation method and if they do makes checking them before each use for signs that they may be close to failure.
As to 3 season to 4 season, I do agree it's marketing terms and pitch location, shelter, risk of snow, where the flysheet ends, inner construction, etc are more important than a marketing label.
Also brand is significant. Hilleberg nallo of a friend survived a bad storm despite only being a 3 season. Another friend on the same trip had an ultra quasar fully geodesic 4 season mountain tent I think with the snow valence too. It snapped a pole. Reason was the rigid geodesic tent survives by resisting the wind, but it has a failure point. The tunnel tent flexed, a lot, but the flex took the energy out of the wind gusts before damage is caused. However hilleberg do over engineer their tents in terms of strength. A 3 season, supposedly low level tent from them is likely to equal or be better than other brands so called 4 season tents.
In your case I'd suggest with due care about where you pitch and the winter conditions you camp in you can get by in winter in your tent. With regards to your tent brand, if its got those crimp holes in the poles get and carry a metal pole sleeve plus duct tape just in case. WC don't supply them with their tents, vango do, but you can buy them aftermarket. Suggest buying one from vango direct, I think they'll sell them on their website.
Sorry about being so negative about the brand of tent you have. I think you can understand why after reading about our tent failure. We only managed to continue with our main family holiday because I had on the spur of the moment stuffed my vango tent repair kit in the WC tent bag just before we left. Vango supply them with all their tents back then.
