Topping Sannies seeds? (kolosus)

Someone mentioned that you shouldn't top a seed thats been breeded for high yields like those from Sannies?

Has anyone topped any of there's for four main cola's and if so what were the results?

Im looking to get 8-10 oz a plant using around 2k watts overall each plant seeing around 400 w

Looking to use topping as my main growing technique not sure if it's better to go with another breed or if to get plants like big bud and kolosus but leave them alone?

LST thats the best style for monsters next to monster cropping. both of these ways you get to keep main cola

So topping should be avoided?

imo yes it stunts plant and divides yield. under the right circumstances such as a very long veg it can produce good results. super cropping is another good method but take alot of practice you will probably decapitate your first few so i would not recommend it.
