Second Banana is Very Good for Solo Heavy

[Spaghettacus]

While Shotgun is best for an offensive Heavy, on defence if you rely on your health pool as a Heavy that doesn't expect to be constantly healed by Medic, Banana is better than Sandvich. The fast recharge is very useful, and 200 heal (vs 300 of Sandvich) is a negligible downside.

It’s also good for healer heavy even if it heals less it can still save someone from fatal damage
