I've not got many more jumps than you ( only 120) and recently returned after a 9 month lay off.
I was basically re drilled on EP's in a harness, given a very thorough DZ brief and then I did a jump from 12k with an instructor who briefed me well before hand on the content of the jump, exercises and procedures etc.
I was initially thinking of doing a refresher but was told it was not necessaryQuote
