Skill Discussions

I am trying to decide what to train for before I undergo neural remap for Intelligence, and I have narrowed down three options.

1. Capital Ships, but at a low level. Train requirements for flying Dreadnoughts, carriers, and Jump freighters, then train jumping skills after the remap. Unfortunately I would only train the ship skills to level 3. Pro: Fly capital ships relatively soon Con: small bonus when flying them until I get another neural remap
Is flying capital ships worthwhile if you're only at lv3?

2. Marauder! Black ops at low level after I get jumping skills. Vargur with lv4, Minmatar BS at lv5. Pro: Vargur is powerful for PVE and PVP Con: I'm bored with missions, I don't like solo PVP with a 1 billion ISK ship, ships are not always useful
Your opinion on Marauders?

3. Tech 2 Light missiles, other weapons to lv4. Pro: start on Intelligence skills sooner, I want to fly a Jackdaw, wider range of applications. Leaning this way because I want to max out exploration skills relatively soon, see cons above.

I would go for option #3 first, then deal with the platforms to use them on later.

I have tech 2 projectile weapons on all three sizes, and tech 2 torpedoes. So I meant lv4 in hybrids and lasers.

Are there other weapon specializations that are particularly popular these days?

Remaps and perfect training times are most effective when you train long skills for an extended period.
If you want something at "low levels" so you can basically just sit in it, all you're really talking about saving is
minutes on level 1
hours on level 2 and 3
half a day to a day and a half for most level 4 times

As for capitals and black ops:
Some of the most expensive ships in the game. You would probably want them trained to fairly high levels if you intend to fly them with fleets in regular PvP.

I'd suggest getting your smaller ships well trained before you step up.
More fights, more experience.

And don't burn your remaps up on a few skills at level 3 and 4.
