Clear durable finish for quartersawn, spalted sycamore?

I am finishing up a quartersawn, spalted sycamore bookcase and will need to plan for the finish. I usually apply some ultra blonde shellac, then wipe on Pratt and lambert no. 38 varnish for most of my projects. I recently did this on a maple chest of drawers and while it looks good, it will be too yellow for this sycamore.


i am looking for some recommendations on other options that have good durability but minimal impact on tonality as this will be in a kids room and house books, toys and many Other random items. The case is 48x 32" so it may be a bit too large for brushing depending on the drying characteristics of the finish.


thx
