Henlo ppl.

Just needed some advice on what is considered fair when trading down spikes. Specifically, red long=blue long + ???

I like to trade down from red long to blue long frequently. And ppl offer very different things, which leaves me confused on whats considered fair. I dont want to be accepting undertrades unknowingly D:

So what do you think is a 'fair' add when someone trades a blue long for your red? (im referring to SPIKE terms).
