PART II - Looking for advice on new bass boat

[G-Man]

About a week or so ago I started a thread called "Looking for advice on a new bass boat". The messages and comments I got back were incredible and thank you to all who replied and gave their opinions.

Today I went to go see Phoenix boats and fell in love.

I am looking at the 618 and the 619 and ask for input so I can make my final decision.

The 618 is 18' 6 " with a Yamaha V150 (2 stroke)
The 619 is 19' 8 with a Sho Yamaha 200 (4 stroke)
Im having a hard time here as there is a $10,000 difference here.

Also I am having a challenge picking electronics. I was told by the dealer that Phoenix offers a Lowrance Elite 5X in bow and the Elite 5 w/GPS on the dash included in the price .(But the Phoenix catalog offers 2 Hummingbird 728??
Which of these are a better option ??

Another question on electronics??
From some of the feedback from the first thread and info I got from the BPS I was leading with the Lowrance HDS8 in the dash and at the bow the HDS 5 with LSS-1 structure scan but these are almost a $3,000 upgrade.Is it worth the spend or go with whats included in the boat offering??

The trolling motor is a Minn Kota Fortrex 80 24 volt

I plan to put whatever boat I have on a float air lift under a covered dock so I was going to go with a single axle trailer with disc brakes vs a double axle??? Good or bad idea??

Sonic hub upgrade $300 ( to use ipod)

Other than these questions both boats have everything..
Dual console
3 Bank Charger upgrade
Ratchet tie downs
Extra Seat Base in floor
Bow step
Phoenix Laser cut step pad
8 inch fixed jack plate
reboarding ladder
rod locker with organizers
Tackle organizer system with snake light
Rotary (lazy susan tackle) up front
tilt steering
tilt on wheel
hot foot
Built in battery charger
LED courtesy lights
ALUMINUM Gas tank
Stainless steel pull up cleats and locking latches

This boat ROCKS!
What do you think ?? You guys got me this far please help me get a boat to my dock.

Thanks a lot.
