Dima may have as much power as any of the best BH-ers, but his techniques are quite incomplete when compared to FZD
ZJK and FZD are technically superior than everyoneelse, I would say FZD's technique has the highest potential, he blocks even better than zjk, he just needs 1-2 more years to develop muscle and perhaps more fingering like zjk has.
if zjk and fzd both have the same achievment, currently I would say fzd has better consistency than zjk and far-from-table looping technique, but zjk has better fingering technique (zjk's 2nd ball receives at crucial points may still be better)
lets see in wttc 2015.
