I would suggest that you use the 30 minute...gives more working time. I doubt that you could do anything with 5 minute,except set line ties, hook eyes, etc. As for the DA i feel it's a personal thing that you will discover for yourself.i've done it both ways,with/without...using DA allows for a somewhat easier "flow" but again it comes down to personal choice depending on lure size ambient room temp etc. good luck!
