For the k 6.1 tour 90. I havent played with it in a long time and whipped it out the last 2 days and boy is it fun! I get TONS of action n the ball not much more power though. Growing as a player has helped a lot as well, i'm shanking less and really appreciate the precision. Some say the modern game doesn't suit it but i think it holds its own fine! Thinking that the biomimetic 100 would be a good buy as this has renewed my love of mids!!!
