Munter is fantastic for tight quarters negative rigging on the fly... have used it for 250lbs although 16 strand doesn’t particularly like it...A lot of guys switched from the munter to a figure 8 for that size of rigging but the munter is an ok tool in the tool box if you use it right. Guys used to take down trees every day with that. But that said, things improve and grow for a reason. That said a porti is simple and consistent every time just the same tool.
As pointed out above one guy said good for 75 lbs I personally do that with leather gloves maybe an xrr at the tree base and the top rigging point. You’d be surprised how much a couple xrrs can help.
