I have something similar to the lead sled. It's a Shooter's Ridge Deluxe Rifle Rest. Stock photo below. I've had it for years and still haven't assembled it. I use a standard Caldwell combo front bag and rear rabbit ears. I think there are better rear bags out there, but the front bag is fine to me. I can see how having an adjustable front rest is superior though. I've read the concerns on splitting stocks, but I thought the greater concern was the more abrupt toll taken by the scope and mount setup if the sled is weighed down too heavily.
