even though there is obv nothing wrong with having larger BR requirements, the whole "more of my roll is at stake" isnt, or rather shouldnt, be an issue provided you have a deep enough BR to sit full stacked (however much you usually buy in for) and have enough left back to add to your stacks as you lose bbs / pots etcetc.

im not telling you to move up as you mention you've just moved to 5NL - but for the future its something to consider.
