Haven’t made them, no manufacturing experience and probably not cheap. Anyone that wants to make them is welcome to the files, just send me a set and do what you will.
Sorry, another text dump, beer:
Harder to break free, yes more grippy. Predictable as in feeling the transition from straight grip into slide, and how abrupt or seamless that transition is.
When you get into powersliding, there are a few things that affect how wheels break free into slides and how predictable it feels. Offset wheels tend to break free easier from what I can tell, rounded lips help a ton being able to feel the wheel starting to slide out slowly from grip as opposed to hard edged wheels really hugging the pavement hard until skipping or sliding depending on the urethane formula.
Really, the angle of the trucks is just one of many factors that affect grip. Raising the height of the board by adding more risers (on topic!) means you get more leverage over the top of the wheel, pushing it down more vertically into the road for more grip. A double dropped (drop deck + drop through) deck during a turn means a lot more force going diagonally or towards the side of the wheels and they will break free a lot easier than a platform higher over the wheels, leading to less grip, more sliding, and more predictable sliding. Hard edged wheels on a low platform and high rebound urethane tends to skip, like HARD GRIP to chat chat chat. When reflex thane was released, we were all running drop decks mostly and had a ton of chattering skipping time, because drop decks and grippy formulas don’t mix well. Low rebound urethane like the old offset 85mm kryptonics on a low platform tends to just butter out and transition from grip to drifting to sliding almost imperceptibly, with low rebound urethane and a high platform being somewhere in between. I have to say, that feeling of low rebound, rounded offset wheels on a low platform, taking a corner feeling the grip transition on a smooooooth gradient from grip all the way into a slide perpendicular to the direction your traveling is one of the best feelings in the world.
Take all that, add wheels tracking forward in their grippiest way and kinda stir it up good with some cooking… there are so many options for whatever your riding style. These are not hard and fast rules, look at downhillers these days, they run low angle trucks in the rear, super narrow trucks which also tend to add grip, hard edged wide contact patch wheels, and they still drift hairpins like mad. Lots of factors… I think they have found a balance over the years of top mount leverage for grip, rear de-wedge for stability and grip, narrow trucks for agility and grip, perfectly formulated thane for as predictable slides as possible without sacrificing on rebound which would reduce speed, with relatively sharp edges for grip.
