Solo player on solo server?

Kind of a follow up from my last post which had amazing replies so thanks everyone for that, great to read them all and certainly sounds like I just need more practice which I shall be doing.

Out of curiosity, as a solo player (to those of you who are also solo), is it best to play on solo servers or expand more? Perhaps a trio server?

I currently play on a 200 pop solo official (weekly) server which is good fun but I've noticed that hardly anyone roams with anything decent and most of the players seem to grub. Don't have anything against this as I have grubbed when needed but it seems like everyone's doing it.

Would a trio server (wipes every 2 weeks) be better? Will there be less grubs and less people with gear fear?

Also my thinking is that if I want to practice my PVP in game, spotting a travelling duo or trio would potentially be easier to spot than a sneaky solo? Could also help with sorting my positioning and stuff out as I'd hopefully see their group roaming before they see me if I'm stealthy about it. Where as on solo, everyone seems to be roaming stealthy, or just across a field if they have nothing.
