Can't figure out how to search for this specific issue but - do any of yall run thunders on decks with super short WB to mitigate the way Thunders extend it?
Yes.
For me at least, to get the similar feel of trucks, I have Indy on 14.5 wb boards, then Thunder and Venture on 14.38 wb, so when set up with bushings how I like them, they will actually behave much the same for all three. I can make all of them turn in a relatively small circle fairly easily without having shakey loose trucks, but I definitely feel the difference if I have all three brands on the same size board / same wheelbase.
Ace is a different story, but I prefer them on other boards, such as longer cruiser shapes anyway, which usually have longer wheelbases, so it again follows the pattern, as they have the shortest wheelbase of all of them.
