Sight.
I have a vivid imagination already. I can visualize memories just by taste, smell, or sound. It would really suck to lose my sight but my other heightened senses and the money would make up for it. Plus my lil bro would be my eyes for me in the case I need to hit up some escort. Dude could describe the chick so I would know who to pick.
The other senses are my life. I would be able to indulge and appreciate food, scents, and music on another level. Astral projection and lucid dreaming would fuel so much creativity.
I'd be on some Daredevil shyt but without the crime fighting, just using my heightened senses in the sack.
If I was someone who couldn't visualize in their head then I'd just go with taste and live a boring ass life.
