Re-use trub?

[DarrenSL]

I'm planning to brew a czech lager tomorrow and have half a jam jar of trub from the last batch that I harvested just over 2 months ago. Do you reckon it'll be ok to just throw this in? I'm wary of the pitching rate and yeast quality. I have some DME so could make an overpitched 2L starter and put that in at high krausen? (not my usual method as I would normally chill and pour off the excess wort).

I would make a starter from it and overbuild by 100B cells and then store that for the next batch. Taste the starter before pitching and if it tastes okay then make your brew and pitch.
