I use 12lb ultragreen mainline straight to the plug. Iv considered power pro but i like to not worry about reeling a swivle into the eyes or tying braid to mono. If i knew a good knot to splice them i might just switch to braid for the thiner diameter that braid has. Thinner diameter line is good for plugs so there is less resitance alowing the plug to dive as deep as posible. Mono has strech though which is nice when fighting a fish, but 30 lb power pro with a 15lb leader wont break either.
