Torspo 321/421/521 Sticks

[bl4 39]

Just wondering if anyone had any experience with the Torspo Surge 321, 421, or 521, sticks. They look like a really good buy for a light OPS, but I've never seen one in person or had any experience with Torspo products. Any thoughts would be much appreciated.

bump. Also wondering if anyone knows difference between 421 and 421 PL. Seems to stand for pro light but both sticks are listed at 440g.
