My main golf partner plays a Blue Tees and I have a precision pro NX7 slope from years back. Generally, we both shoot yardages on par 3s and his Blue Tees is very inconsistent vs my NX7. I'm pretty confident with my yardages and feel that there are issues with his Blue Tees. His fluctuate quite a bit from 5-15 yards during our rounds. In my opinion, I'd go with a precision pro.
