[Antennaware] CG-3000 vs MFJ-974HB on 160, 80, 40m band (or one antenna to low bands)

[Samir Popaja, 7S7V (SM7VZX)]

Mike, please I need your advice:

MFJ-974HB; http://www.mfjenterprises.com/Product.php?productid=MFJ-974HB


Hello, 

I need to solve my problem on low bands; 160, 80 and 40m with one antenna. 

These are my possible solutions (which is better according to you antenna/
tuner knowledgeable people).

The antenna will be used primary for contest.

1. Inverted L (15m + 25m) with radials, feeding with coaxial cable and
CG-3000 in feedpoint 

2. Dipole (2 x 20m), via 450 ohm open line and MFJ-974HB, on 160m the
antenna will be used like T vertical and ground (@20m) 

3. Dipole (2 x 40m), via 450 ohm open line and MFJ-974HB (@20m) 

4. Inverted L (15m + 25m) with radials, via 450 ohm open line and MFJ-974HB

5. Battle Creek Special (on SPIDERBEAM 18m pole) with
(http://www.unadilla.com/traps.htm) traps for 80 and 40m 

*What's the behave of solution 2. and 3. against halfwave dipole feed via
50ohm coax on 40 respective 80m with same height, @20m?
*The MFJ unit has 4 x 250pF, is it enough for low bands?
*Do you know how big is the losses with this kind of TUNER
(CG-3000) which has small capatitors and coils versus MFJ-974HB with little
bigger C and L?

I got some info about AT-502-Tuner by Hamware, www.hamware.de  but it seems
little bit expensive... 

Thank You for all answers/ suggestions.
