double the stakes in my cash game?

[tminus]

ive been hosting a cash game for the past two months which meets twice a week with .25/.50 blinds. usually 5-8 players with varying degrees of skill...most of it soft.

over the past two months ive built a $500 bankroll which equates to ten 100bb buyins.

i was thinking of raising the stakes to .5/1 which gives me 5 buyins and then return to .25/.50 if i lose two buyins.

how do feel about this?
