I can't speak to the EZP specifically, but I do know when I went to buy The Rod at their last release I had a reminder set for the day they went back on sale and less than a week later they were sold out.
Transthetics is very popular. I would encourage you to sign up for the mailing list so you can get notified when stuff is going back on sale, that way you can be sure to get in there on the day of and get what you want. The EZP Junior goes on sale for the first time on 2/8, so if that's what you want I'd try to get in there ASAP on that day.
Looking at the dimensions, it's only slightly smaller than the regular EZP. I don't know what size your Freetom was, but I'd do a comparison of the size (shaft and total length) and weight before committing to one or the other. I personally didn't ever feel totally comfortable packing with anything with a shaft longer than 3.5".
