I'm wearing PI this week.

Going back to it recently after months of not having used it.

What I've found? It's very effective! And there

is almost no smell at all. It's weird though, I almost feel like I can use it without a cover scent (I have the

unscented).

Pretty soon I'll be overloaded with some SOE gel packs and will be using them as cover scent on the

PI. I think PI + SOE is a great combo.

I also use NPA almost daily (but not with PI).

Never tried the

A7...I was tempted to swap it for my PI (especially when I read your threads), but I still think my PI is

effective...it's weird because I can't smell it even though I can smell NPA. I can smell the PI, but

occasionally, and not often. I'll eventually give in and test the A7 though, but I have to save up some

money...

Terry, would you happen to know how strong a gel pack of TE is, compared to say 1-2 drops of NPA? I

have a bunch of TE gel packs that I've never bothered using ...
