Ruger 10/22 Wolff Springs

[EAC]

I went on the Wolff GunSprings site concerning my Ruger 10/22 and was wondering if anyone knows the difference between these kits...

1. RIFLE TUNE-UP PAK - All Models, Reduced Power - without recoil spring
Our most popular pak. This pak contains 1 each extra power hammer springs and 1 each reduced power trigger and reduced power sear spring to improve let-off.

2. RIFLE TUNE-UP PAK - All Models - without recoil spring
Pak contains 1 each extra power hammer springs and 1 each extra power trigger and reduced power sear spring to improve let-off.

3. RIFLE PERFORMANCE PAK - with XP recoil spring
Pak contains 1 each extra power recoil spring extra power hammer spring, extra power trigger and reduced power sear spring to improve let-off and overall functioning.

What is the difference between the extra power trigger and the reduced power trigger.

Thanks.

Apparently each improves let-off...

Just kidding. At first blush, both seem to be referring to the power of the trigger-return springs. If they are talking about lightening the trigger-pull, they are sure talking about it in a roundabout way!

At least, that's the only description that would make sense to me ATM...
