It is almost impossible to give worthwhile advise without seeing the way people interact with their flock. I would love to have a this will sort your problem out answers but I don't.I did read your article. I do like the part about grooming can I do this when I’m holding him. There’s no way he’ll let me do it when I’m not. I have tried to pet his comb he doesn’t seem to like it but maybe I’ll do the grooming. Also what would you suggest when he attacks me. I honestly just grab him by whatever I catch scoop him up and we walk until he calms down a little bit.
Picking them up does often work. I try not to do this because I would end up with an armful of roosters over time.

It's not that I don't understand the frustration either. I've had my share of difficult roosters. I am fortunate in having the time and the interest and the keeping circumstances to experiment and in the meantime I wear appropriate clothing and footwear so when it goes wrong I don't have to reach for the medical kit.
I think the appropriate clothing and footwear is possibly the most important tip. If you feel safe then you will be more confident and the rooster will sense this. Much of dealing with roosters ime is about confidence. With some roosters here it's taken months to come to a working arrangement. At around 18 months old, provided they have hens and the right environment all the roosters I've had here have been manageable. Some are likable and will tolerate human contact; others not so much if at all. I can accept this, but for those who want a pet or a child friendly rooster the you do your stuff and I'll do mine approach won't work.
