That would make a good stand-up routine, but your audience would be too small at each venue.
The adjustable butt plate one is the best. I bought a slip on Limbsaver for my 870TB, which has the Remington pad on it. The LOP is short, so I put the pad on over it. Feels too long now. I take it off and shoot, the gun feels great. I miss a couple, put it back on, the gun feels awkward, but I hit a streak. Then I miss a couple, must be the pad, I take it off.
Don't worry about the cash you've gone thru tho, you'd have just frittered it away on ammo, range fees, and the like.
Did you try changing the stock bolt to the new and improved heavy weight adjustable model, this may of cured most of the other problems you were looking to find a cure for from what I am reading ... Good Luck in the future ... WPT ... (YAC) ...
At one time I played alot of golf. Actually, spent one season as a single digit handicapper. During those years I spent alot of money on every availible training tool, putter, driver, glove ect., ect. Trying to get back to my best form, I was fitted for a measured set of clubs. (Just like getting your trap gun fitted for YOU.) I never bought another gimmeck again. Nothing from TV infomercials, not a new improved golf ball. Nothing... What I did do, was save that money and took lessons and did the unthinkable. I practiced. Going to different golf schools I was exposed to instructors that taught the up and comers on the various tours. At one school (Arnold Palmer, in Orlando) there were two guys trying to move up on what was then called the Nike tour. I was amazed at how much time those guys really practice, not just at the school but on their home courses and driving ranges, doing this even with a full time jobs NOT related to golf.
I never was able to repeat my best year. But went away with a valuable lesson. When, I got into trap shooting I started with a used Citori combo set. I recived good initial instruction at my local club, and started practicing. Now I shoot a Perazzi. Had it fitted once by someone I trust and will not touch it again. Have only three lenses for my glasses and two shooting vest/coat. Every year I find myself moving back and feeling comfortable about it.
If you slice a golf ball with a $50.00 Driver you will probably slice a golf ball with a $500.00 Driver, unless you get a lesson(s) as to why you are Slicing. The same is true in Trap shooting you will miss those straight aways with a $100 shotgun just as well as from a $10,000 trap gun unles you know and understand why...
