555XL or 605XL

I'm looking at 2 balers to buy. Vermeer 555xl or 605xl. No net wrap. Same monitor. 605xl is a little cheaper.
I only put up 500 bales per year. I don't need the 6' tall bale but I like the 5-1/2' bale.

How much more does the 605xl weight?
I would only make a 5-1/2' bale even with the 605. ..... Is it going to be just as tight?

What are your thoughts on either of these?

Thanks.
