Having one of each isn't going to hurt anything, so why not? Every shot isn't a panic situation and could trade triggers if you wanted.

Assuming you could accurately to try to brain a buff, there really is no need for solids, as a soft will brain them.

If you cannot possibly wait for a better shot than one requiring a solid, carry two solids.

I don't see that it will make any difference in the long run, except I do not like solids on buffalo as there is too great a chance of wounding others.

And, if I was ever to get another double, which I doubt, it would be a single trigger. I do not have the presence of mind in stressful situations to switch triggers. I could never get with the program with pump shotguns either, so you can see I am a hopeless case!
