I'm planning to train HN but I would like to hear some of your experience on this.
I prefer to go with HN instead of one on one because I don't want my players to continue rise in JS in this phase of my training and I do need some of OD that HN might contribuite to.
I have 3 key players to train (so 1 pos of HN seems the natural choice) but I could put 3 more that wouldn't be harmed with it. My question would be around the difference between 2 pos and 1 pos for HN, how much difference did you noticed?
