A few years ago there were 3 sub juniors in the doubles shoot off at the grand.
Two had stock locks and the winner had a pro soft.
I watched those boys shoot and decided to get a pro soft. I couldn't get past A class and found out my barrels were poorly regulated.
After I got my poi straightened out things are going great.
Shot a 97 average at the grand and broke my first 100.
I had the same question a year ago and don't regret getting the sps super coil. At first I thought I made a huge mistake but after some adjustments and a couple hundred doubles I don't even notice it anymore. Well I notice it alot after a long weekend of shooting and I'm not nearly as fatigued. Getting the thing adjusted correctly was the key. it's set alot stiffer than I originally thought it needed to be. Would get another installed in a heartbeat.
I've shot a soft touch since 1996, now have a prosoft. Wouldn't go back for anything. Recoil reduction will help you stay in the gun better. I'm sure someone will say a custom fitted stock is all you need to avoid recoil but how can even less recoil not help especially during 300 or 400 target days not including shoot offs.
Another vote for Soft-Touch.
You can add/remove springs to increase/decrease tension to make it work for YOU.
Call and talk with them just to understand the hows, no charge for that justa little time.
Beth is whom I usually talk with, good luck.
I use a PFS, for both the recoil reduction as well as the ability to shorten it down to my LOP, without cutting the original stock. I have to tighten up the recoil spring a bit more for doubles, to keep it from "bouncing".
I was using a precision fit but I couldn't adjust to the recovery time (it seemed to be moving as I tried to get to the second bird). I got a stock loc and shoot it very well.
I had to have the PFS set very soft due to my bad rotator cuff. The recovery time on the stock loc is so fast that I don't even notice it.
Put a RAD system on my ASE Gold at the 17 Grand and after 200 more doubles was really kicking myself for not doing it 20 yrs ago. What a Difference. Have shot over 10,000 rounds since and is one of the best decisions I have made in 40 yrs shooting.
