Like many things in speycasting, to a great extent this is a function of the skill of the caster, and the caster's tolerance for frustration.
In my opinion and observation, for most people, the easiest casting setups are total head length (belly + tip) in the 2.5-3X rod length range. Past a point on either end, say for the sake of argument under 2X and over 4X, fairly definite adjustments need to be made in the casting mechanics. At the short end, if you are using a 10' tip, just under 30' total head length is in my opinion a little short but not super short. If you are a muscle memory sort of caster, used to a more 'standard' 25' skagit, you might find a few more blown anchors than usual and have to work to keep the stroke compact. If you are a watch-the-anchor sort of caster, should not be a problem. If you are a new caster, I personally would advise you to work with both a slightly longer head and a slightly longer rod until you have a better feel for how stroke length, rod elevation, and incline angle affect the cast.
For reference, I use one of the now-discontinued 11' Rio
trout skagits on a 12'4" rod. With 10' tips that is a 1.7X line/rod ratio -- quite short. I don't really have any problem with it, as long as I focus on keeping all the motions compact and really watch where the anchor is going. And for context, I also spend a lot of time casting 70'+ heads (not on the same water, as should be obvious). Switching back and forth is in fact pretty jarring and requires some concentration, it is not something one can do 'on autopilot', but I can settle down into a routine after maybe twenty minutes of adjustment time.
The suggestions about playing with overhang and tip length are valid. But nothing substitutes for properly tuned casting mechanics. Keep your strokes smooth and compact, and stay off the gas. With a short head length and longer rod, you may end up using a little closer anchor placement, so straight, properly placed anchors are essential. Work on those. Watch your fly/anchor, and if you hook one behind or in front, abort the cast. We've already had a thread this year on nose jewelry.
