Wormholes

Solo as in one Player, or one account ;)

10vs10 in w-space tends to be 3-4 vs 3-4 in most cases.

Also a solo stabber screams bait, I used to Moa bait until CCP ruined the ship.

A lot of the advice is spot-on.

Use a cloaky if you want to engage in solo PvP... lots of opportunities for ganking, particularly if you stake out a busy wormhole for several days when they have "zipped it up" and think they are "safe" with good static hole control. People relax, stop using safes for their haulers, stop watching for probes on d-scan, etc.

I also agree with the above: C5 and C6 wormhole dwellers (including yours truly) are a very, very suspicious lot. We have a lot of ISK sunk into capitals and T3s in our SMAs, and the line between a good fight and a roflstomp eviction is thin, indeed. If someone stumbles into our wormhole obviously looking for PvP, we're going to ring our mates over Jabber asking if they want some PvP, because our experience is that every T1 or faction battlecruiser hanging out around a wormhole. usually has a fleet of T3s behind it waiting for someone to jump on it, so we want to have our own fleet to respond. The fights are still "small" by null standards -- typically 10-20 people or so at most -- but if you don't bring the numbers, they will and you'll lose a lot of ships.

Even the "solo" guy running sites is assumed to have at least one -- and probably more -- teammates cloaked-up nearby, waiting to pounce on a potential gank attempt. So even if we want a "solo" kill, due to that assumption we'll ship in with at least a few guys. At worst, your corp-mates whore on the killmail. At best, that neuting Legion or Armageddon we brought in allows us to escape the return blob.

C1 space is really ghetto... people don't even want to run sites there, usually, because it's so unprofitable. You'll mainly catch people doing Planetary Interaction, which is about the most valuable thing you can do in C1 space, and hi-sec day-trippers.
C2 space is rich with PvP, because basically most of it is an extension of lowsec. And with the majority being Lowsec and C2-connected, you'll find a broad variety of lower-skilled PvPers, PI, industrialists, and more.
C3 space is also pretty target-rich. It's the highest-class wormhole most T3s can solo in a reasonable-cost fit (sub-1Bn ISK), so you'll find many doing exactly that. Think of it as hard-core C2, and you're not far off. Most only have one static connection, though, so it's a little tougher to find a healthy chain to explore.
C4 space tends to be kind of backwater. It's mostly the home of carebears who run sites in fleets and are there to make ISK to fund various other activities. And with so many being C4-connected, you end up in long chains with no decent exit from time to time, so you better be self-sufficient!
C5 & C6, we run in gangs for safety, but are eager for PvP and PvE. We jump on bait because we want the fights, but our experience says everybody is in a gang, so we almost always bring our own.

Not really, you have other options too like FW (though there are many warp core stabbed pussies), flying a kiting ship that's able to split and engage gangs, flying a really fast slippery frig (like dual prop frigs) that can pick and choose targets etc. Obviously fair 1 on 1s aren't very common, but you do get them.
