Been using them since 2024. We've spent quite a bit of time before seasons or hunts (2 South African Plains Game hunts) practicing from sitting and standing positions. Have worked well on hunts where the shooting and hunting style lent itself to its use. With a guide, a PH, or another person with you, have them carry it and be able to set it up quickly for use when you need it. Then all you have to is get your firearm settled into, and get on target and shoot.
The regular ones are heavy for long treks afield, so the carbon one is a couple pounds lighter and easier to pack in the field. (We have both.) But still not an item I'd pack on a backpacking mountain hunt. You'd want a lighter version such as a RRS, but they are way more $.
You can get rock solid on them from various positions, other than prone.
As mentioned, some do not like the clamping device, while others make it work.
Really depends on what you are planning to use it for...target shooting or hunting? Spot and stalk vs stand hunting? Varmint or big game hunting? Or all of the above?
