1. No, but not because I don't value the info. I haven't had the disposable income to buy new equipment recently. My wishlist is fully based on MGS reviews, however. When I do get the cash, MGS reviews will definitely influence my decision.
2. I feel more informed about the actual performance of equipment, rather than the marketing hype.
3. No, since I haven't purchased any equipment.
4. See above. New equipment always makes the game more enjoyable, for a few swings, at least.
