I have been doing soft combs as an option with our system for over 18 years, and while my words of caution will still very often echo Dan's (Trap2), above, my experiance in talking to many shooters who use them really tells a bit of a different story. When we first started doing them I really expected many shooters to come back 6 months to two years later, once they quit lifting their head off of the stock, and want a hard comb so that they would be more consistent. In fact, I don't know that I have ever seen this, and the shooters who order a soft comb will almost always order a soft comb on their next stock, and their next one, etc... Gun fit is very important, and Dan is correct in some cases, that the answer may simply be to have the gun properly fit to you, especially where pitchdown and cheek slap are concerned. I will, however, have to most respectfully disagree with Dan that this is always the answer. It is just my opinion, but I have been doing this for too long, and have seen too many stocks that have been fit to the shooter properly, by the best fitters in the country, and still give the shooter recoil problems. Some of us are just more sensitive to recoil than others, especially those who shoot a lot, have shot a lot, or shoot a lot of heavy loads.
My advice Wilson, would be that if you don't really feel much recoil in the face, but are just thinking that a soft comb might "feel" nice, I probably would follow Dans advice and not do it. Also, you might consider whether you think gun fit could be the issue. Lastly, if you feel that you could probably benefit from a soft comb, but want the option of having the original comb (wood) instead, then consider buying a gun without an adjustable or soft comb, and having both done afterward. I have installed many of our recoil reduction systems over the years, particularly on high grade guns, using the original comb, but also made the shooter a soft comb, so that they could use either. I have also done a number of adjustable comb installations (no recoil reduction system) this same way. It costs a little more, but in your case it may be worth it. As those on this sight know well, there are a number of us around the country who do good quality adjustable comb installations, and I am sure that many of them can do an installation with both combs if you wish. Other than possibly Perazzi, I don't know of any manufacturers where having both is an option.
I hope this helps! Good luck. Mike
