OP here. I had older wooden counters before we re-did the kitchen. They were lovingly dinged and marred from many years of use. I'm not looking for a "perfect" look, just concerned about causing real damage to the new wood. I think old wood is somehow more resilient?
Also, my new configuration has the sink mounted right into the counter, where I used to have a sink with a built in drainboard on both sides. I know this is not ideal, but the wood was affordable and we had a small budget.
