Get the F, in the nib is semi-flex. That means the first letter will be a bit wider and depending on what the last letter of a word is, part of that may be a bit wider also.
Also as some one new to semi-flex....unless you already have a light Hand, it will write fatter than F, until your Hand lightens up.
If you get a calligraphy book, there are certain descenders you can/could occasionally make a bit fancy....a bit of it up to 3 X a light down stroke. Most of the descender would be going from 1 X to 2 X.
I do warn against doing that often in that you could unconsciously stretch the performance by wanting just a bit more.
The problem is it is a modern18 K gold and not the vintage 18K alloy so could bend and stay bent. Vintage was better. Ham Fisted =$$$$. Hold the pen lightly like a featherless baby bird...and don't make baby bird paste.
Cross is a nail. I don't know about your Dream Touch.
Is Dream Touch the old 'true' regular flex or is it a 'Springy' nib like a modern MB or a Falcon. That is a nib that has nice tine bend but only goes 2X on tine spread. If so semi-flex is like a 'Springy' ++ nib, in you do have a max tine spread of 3X...it is hard work to try and max to 3 X all the time....And should not be done.
The 1000 is a big pen; Over Sized (and for an un-posted pen...long)...you have to let it settle in your hand where it wants....if it want's to settle just behind the big knuckle at 45 degrees let it, but I think if your grip is light it might feel lighter at 40 degrees at the start of the web of your thumb....or even at 35 degrees resting it's weight in the pit of the web of your thumb.
The lighter you hold the pen, the lower it will settle in your grip.
The less pressure you apply to the nib by holding the pen hard to maintain a high grip angle the better. The narrower the line....that should you wish to double the line for variation it can be done with no big effort. It is semi-flex.
Heavy handedness comes from gripping a pen too hard....striving to hold it at a higher angle than it's weight and length would like.
I am speaking in general because of the 18 K nib. I don't have either Oversized pens, MB149 or 1000. I find them too big for me. I do have some Large pens, and semi-flex mostly in Standard or medium-large pens, 14 K or steel nibs (in steel, Osmia/Geha nibs)....some 26 or so. They spring back well. I have no fear of those nibs bending and staying bent.
Modern Pelikan is reputed to be wider than semi-vintage or vintage. I do not know if that is also for the 1000's nib. It is on the 800/600/400. So an F would/could be an F-M and add the ease of flex write more to a M, if your hand is not light......(There is always slop/tolerance. You should ask for the nib to be tested and get something in the middle of tolerance. In every pen company a Skinny M can = exactly a Fat F.
I made a mistake when swapping in a M nib on an MB for a B nib and got a fat B=BB. I should have told them a middle of tolerance B...or even a thin B.
You do have some 5 weeks to swap in your Pelikan nib for an EF if F is too wide or for M if it is too narrow for you. If you do swap in the nib ask for middle of the tolerance.
In each company's standards are different, a F could be a F-M or M, in another company's standards. & Then you add tolerance so it's never going to be exact this that or the other size.
What you want is that it writes narrower than your Cross M nib...when using a very light Hand.
As I said semi-flex will write wider when one is Ham Fisted. I was still Ham Fisted when I got my first semi-flex a 140. When I put it to my thumb, I knew what all the fuss was all about.
It took me some three months to go from Ham Fisted to slightly ham fisted.
The good thing about semi-flex is line variation happens with out you having to do much to anything. Your normal writing pressure will give you line variation.
Add proper papers and inks and you are off to the races.
