Frankly I'd never choose anything besides flm. my buddy has the extended lcg tvp's by them and they are awesome. They are super thick and they are by far the best looking parts I've seen.
I have used FLM in the past but didn't like the added weight and resulting clumsiness it adds to the model. I have run platinum R/C with better results on both my flux and nitro. IDK if hes still in biz or your budget. But its good stuff and strong as using steal... There are others but i never even considered them.
