Sadly i dont think there is any other way than to buy both boards, try them lightly to see wich you prefer and then use your right to return x-item within x days if still in mint condition (different companies have different policies afaik) to return the one you didnt want and get your money. ive heard though that you dont have this right in all countries, but here in sweden you always get a so called "open deal" wich means you have the right to return something within 3-5 days if its still in mint condition.
