Depends on the quality of the extension and the installation job, and how fast the swing speed and aggressive the transition.   Assuming a good quality extension and a proper installation, 

On something like this I tend to almost always agree with Stuart.   Personally, I will NOT extend anything longer than an inch.  I know my swing is unique and I have a stupid violent transit

I would buy extensions from Rockbottom golf. The part that goes in the butt of the shaft is much longer than what you get from GW, that being said no more thank 1.5 inches.

Assuming a good quality extension and a proper installation,  1" will be no problem at all.  The vast majority of ams can get away with 2".    Slower swingers can get away with a bit more.   Reg flex => 2.5",  ladies/senior flex => 3".

Personally, I will NOT extend anything longer than an inch.  I know my swing is unique and I have a stupid violent transition, but I tried a 2 inch extension in steel and had some issues.  I prepped everything and I am very OCD about my clubs, I think my transition is the issue and since I had an issue I won't do it for anyone either.  Seeing as how club building is something I do for friends and I don't have a ton of slower swingers beating down my doors, if I had, then maybe I would be OK with 2 or longer extensions in steel for them.

 

Now with graphite I have extended longer and had zero problems.  I was experimenting with Soft stepping an old Recoil 110 F5 that was in a lob wedge and wanted to see how soft stepping three times played.  I installed it in a 7 iron and put in a 1.5 inch extension and had no issues.

I wonder how much of that difference you're seeing is the shaft and how much is the extension.    I'm a bit of a outlier in that I don't like steel extensions.  Even when extending steel shafts, I'll use graphite extensions.   I believe how well the extension fits in the shaft is the key to the performance of the shaft and I've always felt I can get a much better fit (easier to tailor the fit) with the graphite extensions.   Start a bit big and sand down to the perfect fit.

Looking at the Rockbottom golf website the extensions for steel shafts are the same ones from Golfworks.  Unless I'm missing something.

Golf Works also has one with extended insertion depth. They call it their counterbalanaced extension. Has insertion depth of 3" versus 1-5/8" of their standard one. Cheaper than rock bottom as well.

 

https://www.golfworks.com/counterbalanced-steel-shaft-extensions/p/bb9087/

 

I'm also 6'8", and am having Golf Works build me a set of custom DBM's. The 7i will be 1-1/2" over standard and require a shaft extension of about 3/8" in order to be able to tip trim to X-stiff flex that I need. The rest of the set will be in 1/4" progression both ways. So the long irons won't need extensions, but the 8-wedges will. The longest will be the 9i with a 1-1/8" extension. I'm leaving the decision on which extension to use up to Golf Works.

I usually insert an extension as much as I extend, be it steel or graphite

So a 1" extension has a 1" insertion depth

A 1/2" extension has a 1/2" insertion depth.

My reasoning is that there is such little force exerted at the very butt end of a shaft.

 

While I'm temporarily experimenting with say over-long driver shaft length, I will readily insert a 1" extension ( very tight fit ) and not even bother with epoxy.

Sweet!! I'm anxious to give the DBM's a try, especially at the proper length for myself. I've only ever swung standard clubs. They are building me a test 7i so I can ensure the shaft works out before I order an entire set. Been waiting on the backordered shaft since mid-March though.

Which one? I love the products of Maltby but I am not fond of Golfworks CS. I previously ordered a 7iron on The PTM and really loved it. Went to order the rest of the set and Discounted. They had to know two weeks ago when I said what I was doing. I’m 6 5 so I am sure it will make a world of difference.

FST Pro 125. Was fitted into DG 120 X100. Looking for something more economical since I'll be using it to build 11 or so clubs. 

 

Yeah, that's not cool. I'd be rather upset about that as well.

 

How much over standard are you going? I felt really comfortable at 1.5" over in the 7i. With a 66g grip and 120g shaft, it was definitely a heavier club. But I loved that as well. Really looking forward to getting my hands on it.

Ha I really wanted the FST 115. They half the price of the score LT but they won’t let me sub them out. 
 

I am going .75 honestly I only really need it on 7-P.
