Seeking input on several clovers

[farmlegend]

Frosty berseem good: deer like it, can frost seed. Bad: likely to winter kill in fall plots
Fixation balansa good: deer like it, can put on a ton of biomass, seems to reseed a bit, more likely to make it through winter, not as competitive as red/white clovers if you want to transition out of it. Bad: doesn’t always seem to take well for me for some reason. Doesn’t frost seed well - better fall planted.

You ID'd some important characteristics. One of the reasons I love alice white is it not only frostseeds wonderfully, but it remains green and desired by deer all winter long at my place, as in serious digging through the snow desired.
