Anyone know any good mods for 1.12.2

I'm making a new modpack. Nothing too big or stuff that's causes s lot of lag. I like weapon, dungeon and technology mods, but I'm open to anything good. Also if you got a modpack on Forge tell me it & how many mods it has and I'll try it out. Thank You.

Advanced Rocketry, Redstone Paste, some Pipe mod (i dunno the name) and others

The best mod for guns and for version 1.12.2 is TechGuns.

optifine. good old vanilla is always the best experience for me.

forge page, very mods list for use
