My 2 cents:
I bought a Frontline-X Big Jerm Mortar from the the Hyzerbomb website. It was labelled as teal and the disc is teal (got a nice red foil stamp). The reason I bought it was, I wanted a beadless star Gator. I should have researched it more. Frontline is star and Frontline-X is gstar. The reason I wanted the beadless star Gator was for mid-range stability with a little more skip than the beaded champion glow Gator.
Performance in the field:
For me, the Frontline-X Mortar is dead straight, even slightly under stable when torqued on hard. If released absolutely flat with 75% power on a RHBH, is goes dead straight and fades gently at the very end. Forehand shots need a little hyzer to keep straight and a considerable amount of hyzer to work hard right. The plastic is soupy, which can be good for certain situations. If it stays in the bag, it will be for low ceiling/low line RHFH shots inside of 175ft that need to skip hard right one or twice and stop dead. The grass I played on was not tight, but fairly high. The Mortar got a nice skip anyway. For that reason alone the disc has value.
As for the mold, it is not at all like a beadless Gator, like many posted before. As for price, I paid about $30 after tax and shipping. I'm alright with that because the disc is rare and the money goes to an up and coming company (and Big Jerm). As for availability, Hyzerbomb has a handful of Frontline-X Mortars in stock now in 4 different colors. They also have a few yellow Recon Mortars. Just bought one moments before writing this. It was $25 after tax and shipping. The first one I ordered from my phone and couldn't opt for a shipping option. Turns out I paid for priority the first time.
All in all, I like the skip the disc has, but dislike the gummy-floppiness of the Frontline-X plastic because is reacts weird when you try to rip it. It's like it needs a second to gain its composure once it leaves your hand. It's a touch shot disc for when you need great predictability and good amount of skip from short distances. Let me know if you agree!
