Which mono for Gp Extreme?

Howdy,
i was hoping for some advice from GP extreme users:

WHich large elliptical mono should i pick?

I am considering 18x12 ellip. mono CT goldstalker or NF advantage.

I've tried to use a large mono but found it too noisy, now all i use is a ten inch mono with settings on shallow and sensitive and have had great results

Thanks Gold Fever.

I used to use an 18 inch CT GS elliptical mono on a 3500.

It was a little noisy on the heavy-mineralised ground, but i learned to live with it. It was very sensetive to small gold, and i don't think it missed any targets.
I had a friend with a 45 go over my older patches and he did not find anything that i missed. Occasinaly you do have to dig a ground noise, but not that often.

I am still hoping to hear from current users of Extreme and big monos. I heared good things about NF advantage and cant decide between NF and CT .
Or is this one of them subjective questions with no certain answer?
Cheers all
