I've sparred many tough people but in my opinion, these are the CURRENT top 10 sparrers. 10 being easiest and 1 being hardest:
10. Moneybaby (annoying and likes to gas up the area. Thinks too high of himself)
9. Wiz (Easy when you keep the bottom half.
8. S.B (Hes fast at move making)
7. Pestrana (cool moves but has a weakness when you cross over him and he runs into bullets)
6. Hero (great at boxing people, even from the top)
5. Red (nice aim bro.)
4. Lux (counting when he used his sweet p90 moves)
3. Riley (throws you off at the start and gets easier near the end of the match)
2. Recurvez (although he has that lag)
1. Ozzy (can dodge amazingly)
Edit: I remember loling when Duke was reset. He was being troll'd. But like the most epic spar I've seen is on my status.
9/11/11: Duke Vs. Recurvez
The spar was exploding with lighting from the sky and bricks were being shat by the gods above. Honestly I thought Duke was going to lose but he pulled it off with his lag. Now he just bottoms spams. BEAR TRAP HIM.
