I understand. I had a driver that I hit all throughout high school and college. It was a cheaper Dunlop one, but I hit it great; when I first started it was one of the few strengths of my game. I cracked the face of the original, but was able to find the same model to replace it and luckily it still performed.
About 2 years ago, I upgraded all of my equipment, including a new driver. Sadly, I don't hit it as well as I'd like. Occasionally I'll grab the old one and take it to the range to try to find that old groove with it, but it never materializes.
It now just sits in my spare bag, staring me in the face everytime I walk by it, wondering how I could dump it for a newer, sexier model.
