TT length is much more important. #2 is head tube length.

you're not optimally fit on the rig. simple as that.
"way too much standover" = compact frames? Hmmm? nmSpunout

sorry, I was assuming std. geom.No_sprint

I've got a semi sloping with lots of standover, it happens to be my most seriously rockin' rig. Darn near 15 with my carbon 1100 gram tubies.

fully sloping frames. No knee-on-toptube stability on descents. Is your Ciocc semi-sloping?

Quantum Pro/Record. It is one incredible crit machine. The AC carbon tubies are really awesome too.
Yes, it doesMel Erickson

But that's a qualified yes. For standard geometry frames having too much or too little standover height is usually indicative of the wrong size top tube and other problems with frame fit. Exceptions can be custom frames and sloping top tube frames. Generally, exceptions for custom frames are due to body dimensions that fall outside the norms (long legs, short torsoes, long arms, etc.) Sloping top tube frames are self explanatory. Other exceptions might be touring frames which tend to be a little taller for a given top tube length than a standard (is there such a thing?) stage racing frame.
Agreed because it can correlate to bar heightjtolleson

On a traditional geometry bike, too much standover generally correlates with low bars. If it a production bike, it isn't coming with 3cm head tube extension so in a sense saying that "standover doesn't matter if the head tube is long enough" is not a realistic analysis.

Unless you've got a sloping top tube, too much standover is going to also mean lots of spacers and a riser stem, not to mention the possibility that the tt will be too short as well.
Yes, it doesMShaw

For the majority of riders inside the bell curve, I agree having too much or too little standover is bad. Those of us built like gorillas have always had problems with standover. I need a 54-55tt, and a 47-48cm st. Until the invention of compact frames, I always had a problem with the jewels.

Now that I have an S-Works and a Road Lite, I'm good to go with the right size TT AND the right size ST.

For road bikes, standover is not really necessary. When you're dismounting, you can always lean the bike to the side, when you're crashing, you're usually not coming into contact with the TT. (unlike LA at this year's TdF...)

Mtn bikes are a completely different critter...

no, but head tube length does...C-40

If you get a sloping TT frame, you pay no attention to standover, but you do have to watch the head tube length to avoid a too many steering tube spacers and/or a high rise stem. With horizontal top tubes, the head tube length is pretty much proportional to frame size, so a frame with too much standover clearance will also have a too short head tube.

I pay strict attention to headtube length. I prefer that the head tube plus headset be 150-160mm so I can choose between 80 or 84 degree stems (with no spacers).

My new Fondriest sloping TT frame is only 140mm, so I either have to use 10mm of spacer, or use a 90 degree stem. It's a minor compromise that I can live with, but I wouldn't want a HT any shorter.
