Didn't see that the Ti's on socal's site but skate wearhouse has them in stock. Havven't seen any since 2018/19 so snap em up if you're still looking.
Two cents on comparing trucks; I find Thunders are the best trucks for flip tricks and truck grinds, espically grinds requiring pinch (Smith, crooks etc). the spread out wheel base shortens the motion required for flip tricks, so if you're coming from another truck you may find yourself whiffling on your flicks at first but if you can adjust you should find that you're flip tricks flip faster and feel snappier.
Thunder's, sitting as low as they do, make grinds (especially pinched grinds), easier then most other brands as the angle necessary to pinch is smaller. The lower, wider ride also makes it easier to keep your weight behind grinds.
Thunders are designed with strictly street skating in mind and since that's what I usually skate they're my go to. If I'm skating park/trans/mini I usually skate Aces as they feel like they were designed for that type of skating.
