Boveda packs in humidor

Want to replace the Xikar bead puck in my #2 humidor and would like some experienced advice here on a couple of questions...
1) How effective is using multiple Boveda packs as humidification in small cedar humidors for humidity control? I'm looking at using a cedar holder with three packs for a small desktop humidor (about 100 to 125 cigars).
2) Is this a durable, long term way for good humidification?
3) I prefer my sticks slightly on the drier side, living in humid FL and am leaning towards the 65% or even the 69% packs.
4) What size Boveda packs do I use?
Please let me know what you all advise.
Thx,
RR
