This is just me, im sure the rest of you are much more professional about the way you do it. but i just run and throw myself into it, im not exactly sure what i do but it works and it doesnt hurt
lol
i dont know if anyone else agrees, but i find that i dont think about it, when the adrenalin is pumping i just get myself where i need to be =s lol
im sure it comes with practice tho, iv'e seen more style in the way i slide over time. just practice mate, the best way to practice is in games where you wouldnt feel as inclined to hesitate. however a few attempts on sum grass (like your garden) would definitely help.
