Buying in short to play within roll?

[automaton_22]

Hi there.
I have recently suffered a pretty serious blow to my roll [rivered; rivered; tilt; tilt, long boring story], and dropping down a level is not really an option [I play party, and the lowest 6max stakes are $25, have no intention of playing FR].

My roll after the recent bad run is $315, pretty seriously under-rolled for NL25.

WHat are your thoughts on buying in short, with say $20, or less, until my roll recovers, to compensate?
