Bruce has several different products that use the same stain names as our products - in our experience, these flooring lines are not all the same color, however (i.e. Bruce's Dundee Plank, Gunstock and Bruce's Natural Reflections, Gunstock are two completely different colors). Our stains may crossover to several of Bruce's colors but the only way to be certain is to compare our stain colors with your particular hardwood flooring.
Other flooring brands use similar names as well and our colors match many of these brands.
We strongly encourage you to verify the colors first-hand before placing an order because all colors do vary slightly from run-lot to run-lot on the flooring as well as our treads.
We do have a small charge for all our samples to help us cover the shipping costs but we include a coupon with every sample pack to refund those costs and encourage you to confirm the stain color before ordering.

Regarding the landing in the middle of your staircase, we recommend our landing panel system. With this system, you use a bullnose along the leading edge and 11" wide panels to fill the space behind it. See:

Alternatively, you can install a landing tread along the edge of the landing and filling the space behind it with your prefinished flooring. Sometimes landing tread can be called a stairnose or bullnose.
