THIS KNOWLEDGE COMES FROM NONE OTHER THAN CHRIS CHAPUT HIMSELF.. Read and embrace the power of knowledge. Hopefully this sticky will decrease the number of repeated wheel questions.
There are so many factors that it's impossible to have one definitive answer on speed, control, traction, etc.
Generally Speaking:
Harder wheels wear longer
Harder wheels have less traction
Harder wheels drift and slide more predictably
Harder wheels steer more quickly from side to side
Harder wheels deform less in a turn, and work well for heavier and/or more powerful skaters
Super soft wheels (72a, 75a) can almost "melt" in hot track conditions
Super soft wheels are easier to deform, and tend to be better for rough roads and/or lighter riders
Sideset wheels slide the easiest
Sideset wheels cone the quickest
Centersets cone the least
Wheels will wear where the bearing seats sit
Large core wheels slide predictably
Large core wheels without a lot of urethane depth feel harsher
Large core wheels without a lot of urethane depth have less traction
Hard edges provide more traction
Round edges have less traction
Round edges and chamfers slide more predictably
Super thin edges slide unpredictably
Downhill turns and drifts and slides are done very differently than Slalom and hard carving. When you have a slide glove down and you are grabbing the outside rail at high speed, you can "man-handle" softer wheels without worrying about high-siding. When you are doing Slalom, you want firmer wheels for "snappier" standing carves so that they don't deform too badly or feel "sluggish".
Low boards with slower steering angles and wide trucks are stable, but "push" a lot because of the sideloads in the turns, and give up traction. Higher boards with steeper steering angles and narrower trucks turn more easily, allow more downforce, and give you better traction.
Slop is not your friend. Precision trucks provide better traction and control. Loose bearings also chatter more - crank 'em down. Try and have your front truck out-steer your back truck by about a 2:1 ratio (60/30, 50/25 for example) in Slalom. You also want your front to out-steer your back in Downhill as well. One simple tweak is to use a 50 degree R-II up front and a 35 degree
DH in the back. Or wedge 10 into the front and 10 out of the back to end up with a 45/25 setup from
DH trucks. Too much rear steering is the devil. It's slow and induces a slide.
If you want more drift in a wheel this size, try Gumballs.
We'll be at Pump Station tomorrow putting Pinks, Limes, and Lemons through their paces.
