I have always had a level 4 trainer. That seems to be the most cost-effective choice. I always wonder, however, just how much more I could expect from a level 5 (or 6 or 7) trainer. Is the difference easily noticeable? Would a level 5 trainer be, say, 15% more effective in training my players? Less?
I have been thinking that if I get a good draft pick this year, I might upgrade to a level 5 trainer. It would be worth it because that young USA player would eventually fill my stadium and provide me with nice merchandise revs.
What do you think?
