Wow somebody is high on their horse today!
I've flown the Fisk arrival ~30 times. I've been to Fisk on the ground. I've watched how hard the controllers have to work to keep us safe and traffic flowing, and it kinda ticks me off how difficult a lot of pilots make it on them.
Since I don't fly a Cirrus I will assume the comment about the 90 knots wasn't directed at me. If it was well the reply is no I cannot safely fly 90 knots. At 90 knots my engine would over heat before I made the approach and I would be totally blind out the front as the nose is so high I wouldn't be able to see the traffic I am supposed to follow.
Perfect reasoning for going to 135. A Cirrus doesn't need to do 135, nor do I in the Mooney. 2200 RPM, gear down, one notch of flaps and I can see just fine in the Mooney.
To your second point, I don't have wheel pants. I have a narrow short wheel base with tinny tires, a fragile front gear supporting an Io-550 and a propeller that is mere inches from the ground.
Sounds like you might not want to taxi on grass, period, at any speed! Since all of the OSH parking except showplanes and pre-arranged FBO accommodations are on grass, well, there ya go.
75% of the Vintage airplanes can't do 90 knots,
And they're supposed to do best forward speed and arrive early in the morning if possible. All covered in the NOTAM. It's those who simply choose not to follow the NOTAM that drive me nuts.
you don't see any of the jets being directed into the grass immediately, they aren't sending DC3's into the grass or many other larger/rare planes.
They're also much larger, coming in from a different arrival, and Tower knows they're coming and can make a hole for them while keeping the rest of the traffic flowing.
Are they somehow better than those of us that cannot or will not taxi in the grass?
Nope. Stop taking it so personally. You fly a relatively rare experimental, and you have good reasons for doing what you do, and you're likely not causing anyone any trouble. Or, at least not any more trouble than you have to.
Going back to the OP, what got my goat this year was the number of people talking on the radio even when it was super-busy, causing some inconvenient and unsafe moments for other people. While on the field, I saw plenty of others not following various procedures as well. Sooner or later, they're going to kill someone. Not cool.
