|"Why can't someone make a spring like the original and do away with the two little springs. Or is it part of the (keep it semi auto mentallity)? Maybe it's that great big knob that has to have more spring pressure. They are fun to shoot and accurate. ..TheTodd|

Apparently not enough for some....

It is my personal opinion that there may be a lesser degree of breakage due to the smaller mass of the re-shaped handle.
My first thought when you wrote that no change was noticed, that perhaps inadvertently you put the original springs back in front of the new buffer.
My 27 works great with the Ez Pull springs and is definitely more fun to shoot.
The only other difference I noticed was a little flame at the ejection port. Most likely due to the smaller amount of force needed to drive the bolt rearward.

I use the Janowski spring kit in my full-auto 27A1. The pull (spring pressure) is nearly identical to a 28 or a full auto M1. The reason it is true is because it has been converted to an open bolt (legit, on ATF form 4) and has it has no spring for the firing pin. The firing pin is a fixed firing pin on the bolt face.
Unfortunantly, the closed bolt 27A1 must retain the firing pin spring, and it must have enough tension to operate the gun.
The Janowski spring kits are durable; I shoot mine on full-auto and after almost 4,000 rounds show no wear that I can see.
The 27A1 is a good example of try to reinvent the wheel. The Thompson in it's orginal full-auto form worked like charm. Now that the gun cannot operate from an open bolt, it has made it more difficult to operate and less reliable.
