Honestly, I can't wait for Motordyne, Ark and others to bring LTH's to market, the more competition, the better for the consumer.
I really don't think we're going to see more than a +/- 5whp and wtq difference between the different LTH's assuming they're all built and designed well. There's an optimum design for the product, the closer to that ideal all the manufactures get, the better, but also the more similar the gains betwn products will be.
At that point, the consumer needs to pick based on quality of materials used, welds quality, and of course, price point.
I'm not saying the F.I. Lth's are the perfect design, I'm not qualified enough to say that, but they are extremely well made, with very high quality steel, and the ceramic coating is a plus. I would def put them above the offerings from PPE (the only other LTH choice for us
afaik).
