I'm looking for a decent complete wheelset that is on the lighter side but also affordable (ruffly $400) I ride mostly park and dirt jumps so the wheels need to be really strong..
My mate has the Spank Tweet 28 evo rims on Novatec hubs and he loves them! The rims are mega strong and look fantastic, but the anodizing is pretty thin and scratches easily. Tweets on Hope Pro 2 evos with some nice DT Swiss spokes and nipples built by an experienced wheel builder would be very nice indeed if you can afford to spend that much. If you're set on a complete build I'd stay with Hope Hoops EX 721s just because the value for money and build quality are so high and the strength of the Mavic rim is very well proven.
I've not put any time on the spoons before, but most of Spanks rims are pretty good at what they are designed to be. The spoon wheelset is pretty beefy as far as I know but the stock build is very heavy (2350g) compared to the other options we've discussed, I'm also not too sure about Spank's hubs or what spokes they use. I'd be inclined to go with a build off the Tweet rims with some DT or Sapim spokes and nipples on some second hand Hope Pro 2 evos just because you'll know 100% that what you'd be getting for your money would be as good as it can be. Hope's hubs can be rebuilt really easily too as all the individual components are available after market, in fact I've got a 10ish yr. old Hope Bulb Ti that had new bearings and a new free hub last year and it's in as good condition as my 2014 Pro 2 evo. A custom built wheel will almost always fit your needs better than a factory wheel (unless someone already makes the combo you are after).
