i think $2/4 is best played with $1s as the workhorse. if you used $2s, you would either have to have $1s on the table as the SB or use $2/2 blinds (which i think is fine actually). i prefer to use $1s just because part of the fun of limit is having big stacks of chips in the pot. if i'm reading your chip count in your pr0n thread right, you have something like 660 $1s. you could just add another 340 and have a rack per player at a 10-handed LHE game. or if you're going to do 8-max, obv you only need 140 more.
for $4/8, if you use $2s (i actually still like to use $1s here, too, but you need a lot more obv, so $2s is fine), i also prefer having a rack per player. and then get enough of the larger denom (preferably $20s imo, but $10s are fine) to fill in at least one more buy-in for each player. then if you still need chips after that you can either let cash play or bust out the peppermints.
EDIT: looks like i was typing at the same time as Payback. i concur!
Here's the thing. I don't want to tap into my other chips because my desire is to have the chips to run one good limit table at a S@P while still supporting multiple NL tables.
