i say it is possible to do a straight nosegrind (or something that is close to) and to do both krooks and overkrooks. if you know what you are doing than you can straight nosegrind. and the thing with not standing straight is stupid, you won't grind a rail perfectly in the middle of the truck, you'll always kinda "lock in" with one wheel, but your back truck can be over the rail!

now please end this stupid conversation...
