Mykhaylo, the LimbSaver pad is unforgiving of any sloppiness while mounting the gun to your shoulder. If you are a little outside of the shoulder pocket, the pad will flex, and you'll never hit anything. The inherent "stickiness" of the pad will catch up on your clothing unless the gun is pulled straight back into your shoulder. If you are not disciplined in your gun mount, and tend to slide the gun up to your shoulder, you will find the Limbsaver to be a frustrating experience. Having said that, the pad does have a unique ability to soak up recoil. If recoil is a major impediment to your shooting, then it may be worth installing. If you are simply after a better pad than the Russian thingy then find an appropriate Pachmayr pad. Slip on pads can be useful, but a screw - on, grind to fit unit is best. I hope that answers your question. It's just my opinion anyway, others may have a different experience.
p.s. I forgot to add: use the exchange of pads to alter the length of pull to the correct length for you. Pads are available in various thicknesses, and spacers are available, so if you are going to the trouble of changing pads, make sure you customize the LOP to fit you. So few off - the - shelf stocks really fit their owners.
