I don't kick with a board very often,
i usually sit on them between sets.
Last scy season I did a few fast 50 flutter kicks
with a board,
from a belly flop dive from the side,
one stroke into the wall open turn
wearing a full B70,
think I went 27 on my best ones
in college i went 28.0 a few times for a 50 kick from a push with a board
Eddie Reese told me
Ian Crocker kicked a 50 scy in 24.6 from a push and
Garrett Weber Gale during 2008 Olympic Training Camp after trials kicked 50 LCM in 27.3 believe it was with a board, not sure how he started or what sort of suit he wore.
Shaun Jordan did a 50 kick with a board from a dive in 23.3 right before or after NCAAs in the early 90's
Gary Hall was a very fast kicker and could kick a 100 scy around 55, think Crocker did a 100 in 54
