So there are a shit ton of variables for a setup, but boiling it down to decks you have WB, width, length, nose/tail, and concave for the most part.
I have 2 setups that I've been riding lately:
1. DLX 8.25, 14.25 WB, 32 length, 6.625ish tail, 7 nose, Thunder Ti lite 148, 52 Classics.
2. Krooked 8.38 Twin Tail, Venture 5.6, Loophole teardrop 52mm. Has an overall 3/8" longer wheelbase.
Setup 1 is way easier for front 180s, lighter pop feel, no complies and 180s are easier, but somehow every flip trick is wayyyyy less consistent. Board feels almost heavy to flick for flip tricks, but it is overall much snappier and lighter. Crooks lock in easier.
Setup 2 is way easier to flick and backside 180, manuals feel pretty good, frontside stuff feels worse. Seem to lock into all grinds better besides crooks, which might be because it doesn't have a nose and my timing is off. Feels a bit more stable
Both sets of trucks are stock, haven't touched the kingpint nuts as they both feel pretty good. From memory these have been my most preferred setups, with Quasi 8.25/8.38 a close second. I had a Polar with Aces I really liked that I felt had my best overall pop aside from that it was an 8.5 and super heavy to flick for any flip tricks.
It's hard to figure out what to go to next or what might be causing the differences.
