Choice of two bikes to ship to Ireland

[Edward The Head]

I've been thinking of taking a trip to Ireland and the mainland for 3 weeks or so next year. I currently own two bikes and while I would like to own a third, who wouldn't, can't afford it. So I've got a couple of questions that need some IMHO answers.

The two bikes I own are a 96 Honda Shadow VLX 600 and a 2000 Kawasaki Concours. The pros and cons that I've thought of are listed below.

Shadow: Pros: light, much better gas miliage, smaller.
Cons: Smaller, or harder to see, much smaller gas tank only 2.9 gallons, no locking luggage and none that I know of will fit.

Connie: Pros: faster, more power etc, much larger gas tank 7.5 gallons, has locking luggage, I have more miles and know more about the bike than the Shadow.
Cons: Heavy, almost GoldWing heavy, in a tip over usually broken footpegs and plastic, so much so that I now carry spare parts, worse gas mileage, much wider.

How much difference in shipping will it be? I know there's no exact amount right now but I think the Shadow is around 300-350 pounds and the Connie is at least 600. Is there going to be a major difference in shipping or will they be about the same? Both have the advantage and disadvantage, the Shadow will be easier to move/park in cities, the Connie can hold more stuff. The other thing is that the Shadow is in need of some major repairs, or would be for that, while the Connie is good to go. I also know how to work on the Connie since I now do most of it myself, something I have not done on the Shadow.

So I guess I really want to know is, is the shipping price THAT much different, if it's not a whole lot then I'd probably take the Connie. Also do most flights for Ireland go from NYC and Boston? Most that I have seen do, does this mean the best way would be to take the bike to NYC and fly with it? I'm in the DC area. Any opionions are welcome.
