I just launched a 2m APRS one with the SBS-12 envelope. Although I'm a 
bit over the recommended free lift of 4 grams. It is somewhere between 
5.2 to 5.5 grams free lift.
This one is Solar-powered only 
with Supercaps. Payload weighs 14.80 grams but after the string and tape
 it is 15.80 grams for payload, string and tape. Free lift  around 5.2 
to 5.5 grams.
APRS on 144.390 FM as well as 144.340 MHz FM every 2 minutes.

Inflated and launched by myself in a light wind with no problems.
Predicted
 flight path is across north GA, north SC and then out to sea near 
Wilmington NC. Probably will stop transmitting just east of Charlotte 
due to sunset.
