As a rec, just play whatever you feel like playing and within your budget.
I don't get it. Why should a rec not consider bankroll management? You can be a rec but profitable, you could have a yearly spending limit and so on.
Because of age and working, I have a pretty big bankroll compared to your average young pro, but I am not going to start playing 50k 6 max hold em MTTs anytime soon. Of course if you have other income, your bankroll isn't so critical, but with staking/grimming options it isn't that important with your young pro either.
Sure 100 buy ins is ok.
