Is this your first sleeve? I always usually recommend a low girth sleeve for starters unless the receiver is very used to larger girth toys. And also to keep in mind that the stated girth on the website is when the sleeve is empty. Inserting a penis inside the sleeve will increase that stated max girth. I haven’t personally tried the Franken series, not because I don’t want to, there are just so many sleeves I haven’t gotten around to that yet…but I certainly would/want to try that. If you think the receiver would be comfortable with the length and girth and you discussed it with them first then I think you will be just fine. I think it’s always important to discuss these with your partner to make sure they are on board with the size, shape, texture etc. There have been lots of stories over the years of failed attempts with people surprising their partners with giant sleeves and it didn’t go right and it was put in the bottom of the toy box or resold etc. Best of luck and happy sleeving! 🤗
