Track & Curved forks
Completlt ignoring material composing them(ex; carbon blah blah blah steel), at least for the most part, I eventually want to get a new fork for my roadbike(that isn't steel), and I don't know if I shouls stay track style, or go with a curved fork.
It seems a track style is more responsive, and shortens the wheelbase some, and a curved fork has a more comfortable ride(for the city and such), not sure if it would lower the front end some, or not. Or am I complely off on my assumptions? As far as the track style it has on it, it's steel, and seems to give harsh ride, but it's the only bike I've had with one.

The Steering Feel is related to Trail * the blade length and the offset are part of that .
longer or shorter Fork crown race seat to fork tip axle center distance and the head tube angle is altered ..
* the line thru the head tube crosses the Plumb line thru the axle . the distance between them is the Trail a distance on the ground .
Measure !
You can get a fork Made (with a Brake!!) , which uses straight blades . the rake /offset is the angle the blades join the crown,
The bend can be a large radius , looks good , not much less stiff ,
or old school, 40's~50's as done before streets were improved ..
straight into fork crown and tapering down until closer to the wheel then a small radius bend, which flexed a bit ,
to soften the vibrations of streets with Brick Pavers..

my track bike has a curved fork. Are you using "track" to indicate straight blades?
The compliance of straight vs. curved forks is a subject that could be solved with testing, however, we'd rather speculate. There really is no difference in geometry, you still want to maintain the same axle to crown. On a steel straight bladed fork, the rake isn't that adjustable, although you can fake it a little.

Straight blade forks use either an offset at the crown or an angled insertion to achieve whatever trail amount the designer wants. Other than that, the only differences between curved forks and straight blade forks is cosmetic and one less manufacturing step in building a straight blade fork (which is the real reason they have become popular). Some people contend that a curved blade is better able to absorb road shock than a straight blade, but it has proven difficult to quantify this in any meaningful way.
So, go with whichever suits your fancy.

So I might as well stick with straight blades, and I'm wondering what materials do aero forks come in, that are 1" threaded, if not any, I'll just look for regular straight bladed forks, when I can afford one. Until then; the fork from my Nishiki Prestige will do, omce I get a set of dual caliper...calipers.
