Imo, it’s not worth the cast, UNLESS you have strong preferences regarding vibrations and shit like that. I prefer cast, over forged…but it’s not that deep. Rn. For me. I’m currently riding cast thunders (usually riding ventures, and sprinkle in some ace, you know, like an unhinged person). I prefer the weight of cast trucks when grinding, and when riding over rougher ground. With thunders, the forged plate makes a low ish truck lower, and exacerbates thunders wheelbite tendencies. For me, with venture hi’s, the forged plate is cool. I prefer the pop of cast trucks tho.
** I believe the all cast are made at ermico in sf, and the forged are made outside of the us. I buy cast, for this reason, but have some forged plates as that was all that was available.
