yes, buy all three of them. i don't have th butterfly looking park one i have the black one that grips from all 4 sides. it's the only one i've needed thus far but it works perfectly. sometimes tough to get it to come off the nipple but it never rounds them off. if it does get stuck, I just stick a screwdriver in between the wrench and the rim and give it a gentle nudge and it comes right up. Dont waste your money buying one of the round ones that has 4 or 5 different sizes on it, that piece of crap was sold to me by my bike shop and it immediately rounded nipples and got chewed up.
