I recently revisited the four major trucks brands.
Below is a ultra stripped-down product review/comparison of each.
Ace 44 AF1 (8.25")
"Squirrel Tanks." These are heavier than standard Indys. I could not get passed this. I constantly noticed it. The stock bushing are mush. Combine that with Ace's shorter wheelbase, and these things ride like "squirrel tanks." Due to non-standard sizing of Ace bushing, there is no easy swap-out for aftermarket bushings. Some fawn over how Ace trucks looks. I am not one of them. I think they look like something you'd get on a Wal-Mart board. Oh, the sound. How could I forget that? Something about these trucks (the pre-oiled pivot cups??) made my board sound like it was just pulled out of a swamp--a horrific water-logged, deaden, thud. I can't deal with that. Oh, they are really expensive, too. And I'm not even going to touch on the fiasco with with their sizing catastrophe. Different is one thing. Dumb is another. Lot of the latter going on over there.
Sound like Swamp Monster.
Thunder 148 Team Hollows (8.25")
I didn't totally hate these. Wait. Yes, I did (but not as much as Ace). They are tad lower than my Indys, and have almost the exact same wheelbase. The turn, however, is very different. It's a much stiffer turn (at first), but then goes kind of quick at the end, and then snaps back to level. Even with softer bushing my trucks felt "tight." I found myself doing lots of tick-tacks. No fun. I tried a few different bushings types and hardnesses in these. Nothing felt really good. They had a decent grind. The slightly lower truck height made my pop feel a little more...flat. These might be better suited for a deck with steep kicks, but I am not about to switch out trucks based on the deck I am riding. The real deal-breaker on these is the baseplate issue. Even if you were to assume that I could make these turn/pop like my Indys, I'll never get passed the Thunder baseplate problem. Yeah, you can nose/tail slide on Thunders. That said, there is less room for margin of error and/or you need a lot more wax. Hard pass for me.
Venture Hollows 5.6 (8.25")
The lightest of the bunch (but only by a tad). Oddly, I liked these more than Thunders, despite Ventures also having the longest (bay far) wheelbase of the group. I put stock 90a Indy bushing in these, and they felt pretty good. Certainly not a super-quick turn, but a turn that felt good, and enjoyable. Weird grind. Metal seems harder than any of the others. Ace, Thunder, and Indy all have a round metal encasing around the axle. Venture does not. Their is more of a "straight wall" of hanger. I feel like the rounded axle encasing of the others helps with grinds, whereas the "wall" of Ventures has a tendency to catch more. I also think these trucks look a little...weird, almost 1960s SciFi-ish (which is normally a great look). The real deal breaker with these, is yet again, the baseplate. There are two problems with Venture baseplates. First, is the outermost hardware mounting holes are so far under the hanger (or the hanger is so far out over the baseplate) that it makes its really difficult to get a skate tool on the mounting hardware bolts. This is just absurd. Second, is the exact opposite problem of Thunders; Venture baseplates stick too far out for my taste--more so than any other truck on the market. The real problem with this is that for anything like a nose/tail slide, the extended baseplate gives you a smaller effective nose/tail (e.g. less space to balance on). I mean, we are talking small amounts here, but it's enough that (a) I can notice it, and (b) it occupies space/causes mental doubt in my head about nose/tail slides.
Indy Titanium 144 (8.25")
I saved the best for last. No baseplate issues. Not too heavy, not too light (these are actually a few grams lighter than the Thunder Team Hollows). Smooth consistent turn (with lots of aftermarket bushings to get exact turn feel you want--super loose, to super tight). Mid-sized wheelbase. Mid-sized height. Every truck listed above has some kind of "problem" with it (weight, turn, grind, baseplate, appearance, etc.). Indy has none of those, at least for me. Everything else always gets compared to Indys, for a reason. A friend said it best, "If you are trying to get your trucks to ride like Indys, ride Indys."
