I have read it. Hence my posts and I have also quoted specific text to comment on.Read the thread from the beginning and you will see how it developed.
In my experience colouring tares makes no difference whatever whether you feed hemp or not......and I have been using them for over 45 years on many different venues
If you want to make tares look like hemp you may as well simply use hemp
IME colouring definitely does make a big difference. So your venues behave differently to others but that's why others do it. There is no definitive way it's just what works for others. And iron tablets (Boots, Supermarkets etc) blacken tares much better than anything I have ever tried. Hemp & tares are totally different when on the hook, how to hook etc etc. Again IME for the majority of the time roach take hemp more readily than tares but tares - if you can get them to work quickly/consistently - are easier to use. This is when it's a fishing race. Catching 150- 200 roach in 5hrs needs to be efficient.
