I don't know why but young GK and STs don't perform for me, no matter how high their Q is. I always like my GK and my STs to be old around 30....... Maybe it is just a coincidence but it works for me.
Totally agree with you. Although i don't go as high as 30 i always choose established players in vital roles. I like a 23+ in CB, CM, and ST. My girlfriend buys 30+ all the time as she says they perform well and there cheap.
