Well, actually I don't know Gabez,

In the old days I tried it 2 seasons, and I lost the treble in those seasons.

I have been going 130s% to 150s% last three seasons, my team seems doing well, I guess there is a hidden team chemistry and the problem when manipulating is finding good internal talented players. I guess I will go with my current generation one more season, then I will try it because they are getting old (most of them are 26) and it's getting very hard to train them.
