Just replaced a Limbsaver that was guaranteed not to melt but did with a Decelerator on my 375H&H Belted Magnum.
Lousy paying twice for the same thing plus fitting.
I am happy with the Decelerator.
Limsaver gave me a free one no questions asked. Mine was a pre-fit Rem. so no charge for fitting. They had a bad batch of material about the time the Rem. pad was offered so this is not the norm.
Limbsaver sure work but for looks and durability I like Pachmayer. I also think the softer pads transfer more felt recoil to my face. On a big kicker or high volume shoot I like the PAST recoil shield as it is the same sorbathane material as the Limbsaver. The pad and a decelerator makaes just about anything tolerable until you go to a 458 Lott or bigger.
