I am putting radiant heating under my wood flooring for kitchen and livingroom (and familyroom but that�s tiled).

My 1976 house in MA doesn�t have central AC nor dehumidifier.
So humidity level goes from 20-80%.

I want to go with 3" wide �" thick ALL rift sawn white oak.
Do I have to go with quartersawn white oak for increased stability?

Here are 2 samples next to my cabinet doors. These planks has 1 coat of walnut stain but NO poly yet. Just a sample.

Left = quartersawn (see the flecks or tiger-wood-ish graining?); Right plank = rift sawn.

Reminder: base cabinets = black-brown; peninsula and uppers flanking hood = white

I think I want all riftsawn, because I really like the straight graining of the rift sawn.
I see the flecks of the qtrsawn as flawed or damaged/marred wood flooring.

Or am I missing something, because the lovers of quartersawn would think I�m crazy to not want qtr.
(when the sawns are bundled, usually it�s only 20% qtr and 80% rift. People buy more boxes just so that they can have more of 50%/50%, leaving some of the riftsawn aside/throw out).

Am I over analyzing this?

Thanks for any thoughts,
Amanda
