I guess you are felting here so you can do the same with J-J+ in the future
IMO if he's not 3betting 8-8+, there's no reason to be felting here for image purposes. Even if he is, he is a nit so he might not adjust his calling range much anyways.
Bluffing on the flop is probably worse than floating and taking the pot away on a blank turn from someone who isn't making a lot of moves postflop.
