In my opinion, FL is a special skill. For even u r very pro in FL, its still hard for u to FL a song which maybe called impressive within 100 PC. Its the main reason i think that is why most of the good players give up using FL. I don't mean FL is worthless, but it needs not only the skill, but also the perseverance and memory, so FC a hard song with FL is amazing. But it is also the truth that one legendary rec of FL to be born needs the persistence and memory much more than the skill. Just like kenji use only 3 PC to FC extacy doomsday diff. Its the skill! But i don't think its possible to FL FC a song with simillar difficulty within even 300 PC,that is the biggest differece. Maybe u will say the rec is with no mod, but have u tried to FC it even with no mod? I don't remember how much PC i take to made it FC, but what i am sure is i take more than 3.
Pieguy is a good play, but just like what mikhe said, he has few impressive recs without FL. If u say pieguy is the king of FL, I fully agree with it. But if u mean pieguy > kenji , i will not agree with it any more, maybe its more correctly with the expression 'pieguy > kenji in FL'.
And i am very poor in hid, many good player do much better in hid than me. In my mind, the best players that i know r : mikhe, kenji, Ashchaos, Louis Cyphre, darksoul, just the personal opinion. And i also see some players become more and more pro, like kanarin, shana ,_Giorgos_ etc.
So its right, the CTB world is competitive, but its also what made the CTB world more interesting, at least i enjoy it.

So just enjoy CTB, there will be more pro players in CTB in the future, thats for sure.
