I just want to make sure i get something that isnt going to pop early
Well no rig will be perfect then! It's happened to the best rigs on the market at one point.
2002 Jav's have all the major freefly friendly features (tuck tab riser covers, tuck main (newer style) and reserve flaps, and bridle protection). 02 Javs risers covers are smaller than the current model Javs.
1998 or so was the big turning point for Javelins to have most of the upgrades.
