restarting career in new mod

[harzfeld]

Since I had been playing vanilla too long, I am annoyed enough about those hostile planes, they always spawned in numerous above me too continuously, and like they had F14 engines with unlimit fuel and infinity of depth charges everytime I surfaced or was spotted which I think is impractical or unrealistic. Now I am trying for a mod that should be only just one plane, not 10, appear within their range during day when I am spotted or show up on their radar, but it should take them awhile to get to where I am depending on distances. So I am asking is there any mod available on what I am talking about? I just downloaded & installed Grey wolves, does it have better and realistic verison than those silly planes from vanilla? If not, is there one available and possible work with GW? Any insight on this would be appericate, TIA.
