Despite Bernard's urggh!, you could give flatwound strings a try. Yes, they'll sound different, not so 'bright' but may be acceptable, depends on your style.

It's all very subjective and my poor ol' tin ear doesn't hear much difference. They are really easy on the finger tips and make a lot less string noise. And it's FUN trying different things.

Why half round? because the second moment of area of the cross section is greater and it's 'supposed' to sound brighter than tape wound.
