Deflection (harder tip)

Has the point of contact changed: no--unless the new tip has a radically different radius than the previous one.
What has changed is the area of contact has gone down (harder tips have smaller contact areas than softer tips). Another thing that has changed is the time of contact is smaller with a harder tip.

Do you mean the OB contact point or the tip/CB contact point?
I don't think tip hardness affects either one.
A harder tip can reduce tip/CB contact time a little, but that has no discernable effect on spin, squirt, swerve, etc.

In general harder tips provide more accuracy than softer tips
Your question missing few facts:
1. Are you hitting with english or center hit
2. Are you shooting hard or soft
3. Is the curvature of the tip the same or one more flat
4. A lot of time when tip is changed the cue shaft gets nice buffing, and becomes very smooth could be that
5. Is your bridge at pivot point for english shots
Harder tips will cause a little more squirt, because a hard tip will compress and bend less than a soft tip. This is considered common knowledge among the players I shoot with, but it is still argued about on AZ for whatever reason.
You're getting a variety of answers and I'm afraid this won't absolutely resolve the question. If you have a look at diagram 1 of article 54, "Return of the squirt robot," on Dr. Dave's page here:
http://billiards.colostate.edu/bd_articles/index.html
he found that the cue with a softer tip produces slightly more squirt. However, as he indicates in the article, this could have been because of the softer tip or possibly a difference in the shaft itself. (The hard and soft tips were on different shafts, though the shafts were from the same batch from the same maker.)
Is your experience consistent with this or spindoctor9's or....?

Truthfully i think there is no difference if you hit CB 100% perpendicular and no english what so ever, with that being very hard to do, soft tips tend to apply spin more than solid tip. If you hit with slight error since one side of the soft tip will grab CB before the full tip in contact, that will cause slight swerve.
Common knowledge based on what? Testing, or because one guy said so, and everyone else fell in line?? It's argued about on AZ, because the actual testing says otherwise. But, the difference between the two types of tips is minute.
A good stroke is required to maintain long contact with the cue ball on high spin shots with harder tips. When I play with a kamui hard for example, slow spin shots have a higher possibility of miscue for myself, often causing apprehension, and a usually a less smooth, less confident stroke that results in less spin. Less/more spin on the ball would certainly affect swerve and throw depending on the speed of the shot. I wouldn't think deflection/squirt would be significantly affected.
Common knowledge, because anyone who has went from a Kamui SS to a Hard on the same shaft back to back will notice an increase in squirt. And if not, they are not hitting the ball hard enough to really squirt it or they are not much of a player...
I don't understand how it is not common sense that a hard object, hitting another hard obect offcenter, will deflect it more than a softer object would. Hit yourself in the head with a pillow. Now try a bat. See the difference?
Let me also say that the difference is squirt is not major, but it is noticeable.
Is the new tip significantly higher than the old one (new Kamui tend to be)?
Greetings from Switzerland, David.

You may think that is a good comparison, but it isn't. :wink:
edit: As Jal pointed out, look here http://billiards.colostate.edu/bd_articles/index.html at 54 and 59-67 for everything you wanted to know about squirt. It will clear up your misconceptions about it.

Sorry TWORAILDAVE but how can this statement be true? Help me to understand.
Thanks

Perhaps I should better state it as my opinion that a softer tip is more
forgiving on shots far off-center. I consider it less grippy, and therefore more
likely to glance off of the ball. I like to use soft spin a lot and find myself
very far off center at times. I like a hard tip, but a really hard tip, like a
kamui hard, in my experience, lead to more miscues. If I haven't loosened
up all the way, I would be much less inclined to shoot an extreme shot
with a very hard tip than with say, a kamui ss. Hesitation of a miscue in
those early racks will cause my stroke to generate a less smooth follow-
through on hte ball which would impart less throw and less swerve. If
someone were uncomfortable with a new tip, this effect may slightly come
into play. That being said, I don't consider triangles very hard.

I meant the hard tip is less grippy
