Limiting to one particular tree only matters on threshold, which should be looked at as taking advantage of a niche. Threshold can be nice but they don’t define effectiveness. They are compensation for other crap you have to deal with, or effectively remove other things you don’t want to deal with. The best overall is a combination of mutations from all trees. Even then its a matter of taste and tolerance. Some combat styles may depend on certain threshold more than others.
Here is a plant threshold, which don’t add much for combat, atomizing a victim. Was built for another style than snake. Note no hydraulics.
