Crazy timing, was just thinking about 151s and got some. Had two skates on some 151 hollow lights, great truck but probably won't be my go-to.
For context, I'm skating 8.25/8.38s mostly and just came from 5.8 Venture titaniums.
Good:
Broke in really quickly, grind nice and the turn/pop feel are all great. Like many people say they're quite twitchy in the turn but it's really controllable and responsive, then again I'm not too fussed about precisely how a truck turns as long as its decent.
The pop feel is good too, I like how low they are, I feel like they would have been a bit much for flatground if I got the heavier team version given that I ride a small-ish board. But since they were so light and low, all my flatground was completely manageable and I don't think it took noticeably more effort than on my Ventures. Things flipped a bit slower though, this took a little bit to get used to but made certain flip tricks 'fold' better and others feel really floaty and satisfying.
Pinch is great too, was definitely getting into my pinchy grinds more proper, though I struggled a bit with holding them since the hanger tweaks differently to ventures and they're a quarter inch wider... feel like a week or so in and it wouldn't be a problem and would be better overall.
No issues with wheelbite either which was one of my biggest concerns.
Bad:
Kingpin clearance is less than Ventures, scraping on smiths isn't fun, I'm sure it would be fine after grinding it down a bit but nonetheless would have liked more clearance. The thing with Ventures is that there's so much clearance at first, and by the time your truck is ground down your Kingpin is gradually worn down, so there's no uncomfortable phase of having to wear out a fresh kingpin with no clearance.
You can still do all your slide tricks just fine with the recessed baseplate, especially if you wax the side of the ledge. But it definitely slows you down a lot on the longer slides. On longer nose or tailslides I was rolling away with noticeably less speed than if I was sliding on the baseplate. That on top of always having to wax the side of the ledge was getting pretty annoying.
Summary:
I think I'm going to go back to Ventures, got a set of 5.8 v-lights sitting around. Probably would skate these more if they slid on the baseplate. You can work around it, but I feel like its such a fixable design flaw that you shouldn't have to... Ventures are also a tiny bit more stable when setting up your feet in awkward positions or when you're going really fast but it's a very small difference, easily negated by the added responsiveness of Thunders. Might set these up on a fuckaround setup in the future though, feel like they'd be pretty perfect on a non tech board where I'm not doing smiths noseslides and tailslides.
