Goey

It is all very well to keep a stylish steed, but many a horse is "a good 'on to look at" which is not "a good 'un to go," and I for one would rather have a goey one than a showy one.

I slowed her down, but she was goey and irritable. In fact, Rune always felt like a revving engine under me, an engine that wanted to shift into a higher gear.
