vjsinger - I have to say I'm quite pleased to see a golfer who has just gotten into the game and says they are serious about playing the game and using blades. I truly believe that blades are the best path to really learning how to play the game.
That's one of the things that appealed to me about Lag's ABS teaching was reading about how and why blade irons are good and how and why CB and GI irons are really bad for your game. I pretty much grew up on blades, but also played some player CB's intermittently in that time. I always hit the ball best when I was gaming blades.
In my college career I showed up with some super small Ram FX Tour Grinds. You could stir your coffee with those bad boys. But, my coach didn't like them and told me that I needed to start 'playing for my misses' and the next thing I know I was hitting some Titleist 962 CB's. To make matters worse, clubfitting was in its infancy stage and I was fitted with 1" longer graphite shafts. UGH.
My swing went down the tubes and A MAJOR REASON why I quit the game for 8 years was the confusion and frustration over equipment.
Anyway, I do play with my Hogan's every day. In fact, I simply cannot hit my Mizuno's, which are about 2* upright and +1/2" longer. In fact, that's why I'm probably going to the Scratch Golf HQ in Tennessee next week...my wedges are now way too upright for me and I really can't hit them well at all. Everything is fat or a big pull.
My IPT's and Apex PC's are 5* flat. The 5-iron is a 55* lie angle. The IPT has a 5-iron length of 37.5" long. The Apex PC is 37.75" long. I think you're fine at 37.75" or 38.0" for the 5-iron. Lag actualy has his 5-iron at 38.0" long. With my IPT's, I just play them 1 club longer. But because I can hit them better and more consistenty, the loss of distance is not an issue. I actually hit the Apex PC's just as long as my Mizuno's.
My IPT's are a D-6 swingweight. The Apex PC's are about D-7. If the clubs are light I start firing the hands too early instead of getting into pitch elbow and then firing the hands.
