Towed Array useless?

[688iGuy]

So I have been lurking on this board for some time now, was a big fan of fast attack, then got out of computer games for a while, then came back and found out about DW, and just yesterday I finnally downloaded the lwAmiz mod, and one thing I've noticed is there seem to be no definite adavantage to the use of the towed arrays now, it seems that the spherical is just as proficent if not more at picking up contacts. I thought the whole purpose of the TA is that it is more sensitve and picks up distant low frequency tonals that the spherical dosn't. Does anyone know the stats on the sensitivity of the towed vs spherical for the mod? I'm just wondering if im just making this up in my head or if the towed array is somewhat worthless with the mod.
