Actually now that you mention it, there are also special PU wheels for rain and it sticks like mad. Also durability is lower and I think rolling resistance is higher ?
Edit : also you usually just swap the middle wheels not a full set to keep nimble front and rear wheels.
Do you think you can try and record your apex corner speed? With a mic included earphones or headphone or BT headset and a vocal speedometer ? Or maybe a smartwatch haha
Thereās a free app available on Google store, I didnāt have enough battery yesterday to run both Strava + Real-time vocal speedo so went for Strava alone.
Hmmm actually an HUD screen in helmet would really be a game changer for this type of racing 
You can get away with flipping the Cones in cases where the hanger / kingpin space is filled as with a spherical or the SZ surfkeys, otherwise there will be unpredictable sideshift as the bushing attempts to find the bushing seat wall. This can also lead to sideloading the kingpin with a mechanical lock and eventually kingpin failure which can be catastrophic. Please pay attention to what is going on, this is not for the faint of heartā¦
Thanks for the warning Brad. I will pay attention. I look foreward to do the hanger mod so this doesnāt feel necessary. Or maybe the tkp is just the right way for me to go.
I have found the SZ TKP best for maneuverability without much lean and not that suitable for high speed due to the arc the axle follows
I am still a cannonball run type of guy, open world street courseā¦
I have learned the following since last updateā¦
The weather have been pretty nice so I have had some time on the street where I could dail in the trucks. I needed more turning so I increased the wedge in the front from 57 to 65 and still had the cone bushings flipped. But this made the front truck do a āclonkā movement where the it all of a sudden shifted quickly when leaning. So I flipped the bushings back to normal.
This took away the āclockā movement. The 65 front truck felt pretty good and I was eager to try it on the track.
But there is still something thatās not dialed in. It felt a lot better than last week, but I was still far from being fast. My gut feeling tells me itās the turning because of the longer deck. It feels like the changed turning from the longer deck canāt be compensated so it feels good. I could try to wedge even further but something tells me thats not going to solved the problem.
I simply donāt feel that the longer deck I have tried the last two times is ideal for the track I am on. There are different things that makes me say this.
First the turning has changes as I describe above and I feel that I canāt compensate through dialing the trucks and bushings.
Second it seems that I do not use the full length of the board. I naturally have my feet closer than the full plantform. If I dont use the full platform, I canāt see why I should have the longer platform as it changes the turning as I described.
Third, when I force my self to use the full platform it ads to the impaired turning.
Fourth, It feels like the deck is too wide. I need to have the the edge under my feet when turning in order to get the lean I need. Therefore I have to move my feet. I now many of you say that I should not move my feet but I have to. If I dont get the edges under my feet the turning sucks. I want to try a board that is narrow enough that I have both edged under my feet so I dont have to move them. At least where I have my feet. When the rest of the board can be wider - I donāt know. I am in the proces of learning to press decks so I will prototype my way through it in the time to come.
Or I should see what bindings might do.
On the positive side the longer deck did give me more stability and a better platform for accelerating and braking.
I will change back to the shorter deck and see if I get back to being fast again. If I do I know that this deck was not ideal for me. And then I am eager to set up the Xapham for the street with the sixshooters 
But on the shorter deck, I did feel that I needed a longer one. So maybe a deck in between. Time will tell.
Holding out for the hanger mod is a good idea. Also is there room for shortening the wheel base by drilling new baseplate holes. Shortening the wheelbase 40mm could be a step in the right direction or make the difference. Research and development, donāt be afraid to chop the deck. Narrow that thing up and modify it to what suits your needs. Its a beautiful deck. In my eyes performing a function is what makes a deck beautiful. DH guys chop cut and customize their own personal performance details into deck design.
