Which version are you running? I'd just keep it on 18.104.22.168.
It's entirely up to you which graphics mod you want to use, but I would recommend Icenhancer. I personally love this one but some people say it's too bright: http://www.gta4-mods.com/misc/icenha...phic-mod-f9503
Most of these mods suffer from a bug know as 'the red sky bug' which means the sky turns red at a specific angle (sometimes, not all the time). I don't mind it all that much but some people are picky about these things
If you decide to use the one from the link I gave you make sure you use the files from the beta folder (for 22.214.171.124. and EFLC). There are some others out there that are for the same patch but if you have your mind set on one intended for 126.96.36.199. you'll need to downgrade indeed.
Oh and no I haven't seen any of those shirts
