I'm surprised anyone is releasing new chains in this market. The LS already has a ton of options out there - both for singles and doubles. Would be interesting to hear what niche they're trying to fill.

It seems like most people ultimately end up with something on this basic spectrum: OEM LS2 (now superceded by C7 chain), Katech/C5R, IRL. Those 3 steps cover pretty much anything but the most wild combos and are all very proven chain setups.
