Just a suggestion, and no, I'm not disparaging the Angler's Roost bamboo blanks.

I'm not aware of your budget but I would suggest a Dennis Stone ferruled solid hex blank.
Google Stone Rod Co. The price may seem high to you but in actuality it is very fair.

And, if you're wanting a true 3 weight, I would discuss the 6' 8" 2 piece Thomas Fairy taper with him.
It's the truest 3 weight bamboo rod I've ever cast, less one.
