Lengthening Irons

[Gilly]

I have always played irons that were +1 in length and loved them. However, my current setup is standard length. What are typically the effects on a shaft when you lengthen a club +1? I assume it create a "softer" flex? This might be an issue since the shafts are S300's and I was fitted for X100 or PX 7.0...Yikes, this might get expensive.

Lengthening the shaft an inch will also increase the swing weight by about 6 points, I believe.

Hmmmm, I understand swing weight, but have no idea what swing weights I've been playing in the past. I have no idea what an increase of 6 points will feel like. Like I said, I have always played +1 clubs so I'm assuming this won't be much of a feel difference on my end. Anyone else have some input on this topic?
