Do B250s and B350s require much prestretching to keep the neck inflated? Are they generally tough to neck?

Re: Necking a large Belbal
I have no experience with them but I've heard that they're really hard to neck, probably impossible to do safely. That would make sense, since they're fluted and pretty big. Reviews for them on Balloons United say that they're like Q24s but not really neckable. -

Some pre-stretching and a good amount of stretching during inflation is recommended for the Belbal 250 and 350 if you want to get a good neck inflated on them.Comment
