I've had the Stages PM just over 2 years now.
Ahhh, just (wrongly) assumed it was a new one! Sorry, couldn't remember who had one!
It was the 35C that came on my winter bike. I think I'll try them at a slightly lower pressure. I keep forgetting that I'm 20 pounds lighter now so I need to adjust my tyre pressures to suit! The tread is a bit less aggressive than it appears on the photo and thankfully doesn't feel like a treaded tyre on smooth tarmac.
After reading a few of the reviews I think I'm after something with a bigger tread, I want to try them on some trails so there'll certainly be some mud around which they are not ideal for... They read as more suited to gravel/grass/dry trails.
Now I have a new bike (BennyC's old Propel Advanced 1) I'm looking at potentially upgrading the wheels to something a bit better.
The standards are the 30mm Giant P-A2 Aero's and ~1770g I believe.
Much of it depends on what you're riding - if riding on flat terrain and outright speed/aero is your main concern (TT'ing/road racing) then don't let weight decide, let depth and aerodynamics decide. Although there's not many places in the UK flat enough for just going as deep as possible (60mm!?) without having a tricky time in the crosswinds those areas are largely exposed to. If you're after more of a mixed/rolling terrain set (like much of the UK) then you're after a combination, but at a low budget you're better looking at lightness with some depth as an alternative to the P-A2's (which are deep and heavy). I feel you'll just have more contrast to what you'll have already so not wasting money...
Aero : Weight : Price. Lots of people traditionally say to choose 2 of those factors at the expense of the 3rd. Thankfully modern wheelsets are very well balanced and not quite the compromise traditional wheelsets used to suffer from. You'll find lots of info on most with numerous reviews with real world tests. Use the internet to your advantage 'hedge your bets' and come up with a shortlist of 2-3 (minimum) which review well meeting your real world criteria and then hunt around for deals on them.
The Vision wheelset linked are marginally heavier with being only marginally deeper than the Giants. I wouldn't say worth it unless you were replacing/selling the Giant wheelset rather than keeping it (and can get a good price for it). The Vision rims are wider so would work out more comfortable (as Giant off the shelf tend to be more traditional narrower widths). I've had painful experiences with Giant wheelsets and in my opinion they're not worth spending too much time on if you kept them and have issues in future (the Vision 35's hardly being 'expensive' as a replacement). Even with that view I personally wouldn't replace them from day 1 as you'll probably struggle to sell for decent enough value (being a used wheelset) to cover a large enough lump of the Visions.

These
32mm sub 1500g Cosines seem like a great option?
TL;DR : Keep the Giants unless you can get a good sell price, if you can, then buy the Visions. With an aero set already (Giant/Vision) look for a lighter set with some marginal aero properties as a replacement, you'll notice more difference on rolling terrain and start/stop kinda riding. To be honest with your fairly low budget you've probably better saving up for deeper/lighter in future, rather than now. If you can afford the Visions now, without impacting future wheel choice, then go for them! Also flogging the Giants...
Anyone
flown with EasyJet recently...?
