Yes

Hmmm,  unless you're really small, 104's might be a  better choice for 
weighting and getting a decent amount of gas.    get rid of ankle weights.

I use no weight w/ 104's unless a really long dive w/ three layers, then I 
use a 6lb v-weight.  I use the same v-weight for 95's, and about 20 lbs 
with a single 80.  (Which I've dove *maybe* once in the last year)
