A pen for 'every day carry' in High School?
You will be taking your pen in to an environment in which you and it will be surrounded by large numbers of the most dangerous animal on the planet - teenaged humans.
As such, one must consider that it is an environment that has high risks of theft and/or damage by classmates.
Accordingly, I would immediately disqualify expensive pens - those should be kept for use at home.
I would also disqualify pens that can only be filled from bottles, as a High School is not
an environment in which one wants to be carrying a bottle of ink around.
Sure, you could
use a piston-fill or sac-fill pen with a high capacity, but doing so would require
you to remember to check its fill level every night
. Piston fillers also tend
to be expensive, and so not worth risking in a High School.
In my opinion, it is less-risky/more-sensible to buy an inexpensive cartridge/converter pen, and carry spare cartridges to school.
I would advocate pens that take cartridges that have high capacities, such as Long
International cartridges (i.e. not ONLY the Short Internationals) or the proprietary cartridges from LAMY, Parker, or Aurora.
I do not think that you necessarily need
to buy a metal pen, as metal 'pencil boxes' (we Brits call them 'pencil cases') are cheap. One of those would also keep your spare cartridges safe in your school bag.
You have already said that you do not like the grip section on the LAMY Safari/Vista/Al-Star, so although they are excellent & robust pens for students, they are of no use to you.
In my opinion, a LAMY Studio is a bit too expensive to take in to a High School.
Pelikan makes a range of pens for use in High School. They take Long International cartridges - so you can get cartridges that fit them from many manufacturers, not only
The 'Pelikano' has a round grip-section and an ink window so you can easily see how much 'ammo' you have left. They are available with 'Fine' nibs.
The more 'grown-up' Pelikan Twist & Stola III are ONLY available with 'medium' nibs.
If you are quite sure that you want a metal pen, Luxor in India still make the Parker Frontier.
It is only available with 'fine' nibs, and it has a round grip section.
I bought one from Amazon Marketplace, and one from eBay. Both are lovely smooth writers.
The design/construction of them is also superior to e.g. my Frontier made in 2005 in the U.K.
The modern Frontiers made by Luxor do NOT (in my experience) have the problems with their caps, or plastic/rubber on their grip section that wears off, which plagued older UK-made Frontiers.
Their nib/feed unit also simply unscrews, which makes cleaning them out really easy
They are cheap by US or UK standards, and they look more 'grown-up' than Pelikanos.
Once you leave school, you could use them at work without them looking like a 'School pen for kids'.
They are limited to using proprietary cartridges from Parker or Aurora, but those are high-capacity and available almost everywhere.
I advise you to read reviews of any pens that pique your interest before buying them. And, if possible, to try them out in your hand (IF you can find a bricks-and-mortar shop that stocks them).
