Grip slipping during swing

[B-Con]

Last summer when I had just started to get serious about golf I hit a huge mental roadblock. Swinging the club with the clubface square to the plane felt wrong in every way. It felt like the weight of the clubhead was pulling back on the club wanting to pull the clubface parallel to the swing plane. It felt like, no matter how hard I tried, I couldn't shake that terrible feeling of the club slipping due to the clubhead's resistance. As a result, I developed a few bad habits. One was gripping the club too hard to keep it from rotating, another was opening the clubface very early and closing it very late in an effort to keep the clubface parallel to the plane as much as possible. I convinced myself that the problem was mental. I have some weird mental ruts that I can get in with bad imagery of my swing, and I thought this was another one. Going into the fall and winter my iron play improved a lot and I worked hard on keeping the clubface more square to the plane and loosening my grip. I thought that I beat the problem for the large part. My iron play got a lot more consistent and I've carded 3 consecutive scores of 91. Not great, but a far cry better then where I was last summer. This last week, as we get a mild dose of heat and some humidity here in north-east TX, the problems of last summer came back. I felt like the clubhead was completely misaligned during the swing and I felt like I had to grip extra hard to hold onto it. My shots were a wide spraying variety of pushes -- for the past 6 months I've been battling pulls and hooks, not pushes. It literally felt like the club was resisting and slipping in my hand as I swing. I had the worst driving range sessions in the last 6 months this week, and almost every shot with a club that hasn't been wiped down recently feels slippery and terrible. Once I felt that same problem come back, I instantly realized it wasn't just in my head. I occasionally backed off the ball and took two or three consecutive practice swings. Almost every time the clubhead would end opened by 10 - 30* compared to how it'd started. I'm convinced that the club is slipping during the swing and rotating more open. The feeling of it slipping is absolutely terrible and throws me off more than anything else. I sweat profusely, so that itself can make my grips a little slick to begin with, but I didn't have this huge problem all winter and spring. Now that there's humidity I can't seem to make decent contact with the ball. I have Lamkin Crossline grips on all my clubs. They're not the best at handling moisture, but I've found them to be better than others (such as the GP Tour Velvets). My grips are only 9 months old, I keep them in good condition (indoors if I'm not using them), and I wipe them down every time I use them. I just compared my old ones to new clubs I got gripped and they're reasonably similar in feel -- old grips definitely aren't the problem. I have a Callaway Warbird glove, which while not being the most tacky of gloves has a decent amount of grip. If I wipe the grips and my glove down after every shot I can maintain a half-decent feel, but it's still not nearly as good as it is without humidity. There are millions of golfers who play good golf in humidity. Does anyone else have poor grip problems because of it? Any tips on dealing with it? I know this may sound kind of silly, but it's the biggest obstacle I face at the moment. I cant's wing a club that I don't feel like I'm in full control over.

I'm from Oklahoma. It basically has the same climate as most of Texas. I play the Lamkin Crossline Full Cord. The cord gives me great control, even with sweat, rain, ect. I recommend them to everyone, and now all the players on my college team use them. Also, having a towel on your bag is handy. I have two(One for clubs one for me) Also, if you haven't been fit for your clubs, go to golf galaxy and see if you need your irons bent. If they are too upright or too flat, it makes it harder to keep a square clubface at address. Good luck with your game.
