No right answer. Keep lighter fluid and a towel handy, because it can be sticky even when it doesn't appear to be. Change when it feels like you should.
I am more interested in the comments about using white tape. It wasn't so long ago most guys didn't use anything on the front edge. I did, but rather than tape I opted for cork sure hooks, which are getting hard to find. I now use white tape, but I don't think it maintains the feel for me as long as the cork.
