Cant decide on lift height

[Gator70]

Im needin to put a lift in my 70 K15 and I cant decide on how much to lift it. It needs new springs so I figured this would kill two birds etc...

I dont want a monster but something that will look tough.
Im considering a superlift 2.5" or 4".
Can you guys post some pics of your lifts so I can get some ideas. I dont think that I'll go any bigger than 33" tires, probably stay with 31's. Im actually running 16" wheels from my 98 on it with the standard Z71 size of 265/75R16.

Any help would be fantastic

Thanks.
