LC: replenishing stack while playing

[zipppy]

Long time STT player, first time SSNL poster. Didn't see this in the FAQ, so I thought I'd post quick to get some insight.

If I sit down at a table and lose a few pots initially, at what point do I reload my stack up to 100bb? Should I be doing this anytime it drops below 100? Do you wait to bring more money to the table until you get down to 75, or even as low as 50bb?

Is this a personal preference kind of question, or is there a standard rule of thumb? I'm sure it's optimal to keep your stack at 100bb+, but I'm wondering if you all replenish that incessantly.

thanks,
