First of all, Wyandotte roos tend toward being combative. I had one who wanted to have a boxing match every day where he would fling his feathery body at my legs and I would slap him. Rinse and repeat a dozen times. I hadn't handled or cuddled him especially much while he was growing up, either.
However, growing tired, literally, of the daily boxing matches, I began to grab him up and holding him tightly under my arm, I would carry him around. During the day, I would often hold him in my lap, holding him tightly against my body. After several months of this, the daily boxing matches stopped.
Now I have a four-month old Brahma cockerel. He's very high strung and full of the devil. Several times a day, I make it a point to call him to me, slowly reach out for him, and bring him in close. He usually squawks and complains, struggling to get away, but I hold him tightly, speaking calmly to him until he settles down and melts into my body. After several minutes of speaking calmly to him and stroking his head and cheeks, I let him go, but only after he's been calm for awhile.
This will teach him that he can trust me, and when the hormones begin surging through his body, hopefully we won't have to re-establish trust and he won't think he's got a point to prove.
This worked very well with his daddy who didn't flog me, but he was so mistrusting of me that he would deliver vicious bites when he felt threatened. I believe you can establish dominance over a rooster by treating him firmly instead of violently. By holding him close for extended periods, you are sending him a message than you control his mobility, but that he has nothing to fear from you, either.
Another thing to remember as your rooster comes into his hormones like yours is doing, is to refrain from any sudden movements around him, especially with the hens. He'll be on edge for the next year, and you need to spend this time establishing that he can trust you. Go ahead and keep handling him as you used to, but do it more slowly, deliberately, and firmly. Having tight hold of him, go ahead and get right into his face with yours. Do not release him until he's very calm and limp, demonstrating that he accepts your dominance over him. After releasing him, if he approaches you in an aggressive manner, immediately repeat the exercise. Affirm this every single day without fail.
You can have a good roo without being abusive. But it takes commitment and lots of time to achieve.
