affect ride characteristics? Differences between 73, 73.5 and 74?

Thanks.

On a mountain bike, shallower HTA's make the bike more stable at high speeds, but the wheel flops around at low speeds. On a road bike, slight differences are less pronounced, especially if the angle is correctly matched to a fork of the proper rake. I think road bikes have different HTA's for fit rather than handling--you can get different top tube lengths and still have a similar wheelbase.

The angle of the headtube does absolutely nothing for the RIDE of the bike. It only effects the HANDLING.

Head tube angle and fork rake define "trail". Trail effects steering and handling. Wheelbase has nothing to do with steering but does have some effect on handling.
Take a look at this:
