Have had beautiful weather lately up in Oregon, haven't been posting here much, but this topic certainly has piqued my interest. The Stalker finds its way in and out of my bag a few times a year, but I think this time its stuck for good, here's why...
It truly is a specialty disc, the Stalker is simply meant to be thrown as an extension to the Buzzz. At my power level I throw my Buzzz's on 10-15ft high line drives out to 350' or so, I can push a Buzzz to 400' but it requires so much air and movement it's just not an effective golf shot for me when I can easily disc up to a PD and throw that same 10'-15' line drive out to 420'
Naturally because it's a specialty disc it ends up filling a very small and very distinct role in my bag a straight-flyer in the 350'-360' I don't think there's another disc to even compare it to it's a true hybrid. It pairs the HSS of a more stable driver, with the LSS of a neutral flying midrange.
When you compare it to TB's, P-PD's, and Eagle X's they all fade much more than a Stalker. A seasoned TB is probably the closest but at that point you won't have Stalker-like HSS. Eagle-L's, The Leo, FD don't have the same HSS while being close in terms of LSS.
I suggest everyone that's overlooked the Stalker at some point, like myself, revisit the mold use it to extend their distance on midrange type shots, as opposed to working it on a variety of of fairway lines. As long as you're throwing The Stalker in the right situations it really shines.
