the Pulse!! and esp Force, both 172g, sidearm, I was a backhand thrower until the past 2 weekends of playing with sidearm and driving almost 400ft. I got my Pulse about 380-385ft and Force usually lands about 10 to 20ft behind my Pulse, and Flx Surge (also 172g) usually lands about 10 to 20ft behind Force.
I havn't thrown the Surge much yet with sidearm though. Backhand the FLASH easily my farthest driver ESP plastic and got 3 of them, ranging from 170g-172g and they always out drive my Surge by 20ft or more (drive about 310-330ft backhand).
But anyways, Pulse is usually the first one I grab for bombs or just about any of my drives sidearm. The Pulse in my opinion isn't very good backhand, at least not for me, I probably don't have enough snap backhand for Pulse. Backhand I can throw the Flx Surge in almost any winds, vs the Flash doesn't handle it as well when it's really windy.
If your a backhand player and havn't thrown or owned a Flash I would HIGHLY recommend it.
Depending on how Im throwing that day its either a Z Avenger, Z Predator or a Z Force. If I can flex my Force I can get it around 450 but some days I just cant do it. If its a tailwind I grab the Avenger, if its dead calm I grab the Predator. I used to throw an ESP Surge pretty far but something happened where I turn them over all the time. Even brand new. I can also get an ESP Flash out there pretty far but I lost my accuracy with it a couple months ago. I dont know what happens where certain discs stop working for me. But there will always be those for sures like the Avenger, Predators and Forces. I recently picked up a Z Surge SS. First time I threw it I had to be almost 500 feet. I dont thinking Ive thrown it over 400 since then. I do like the natural flex shot it seems to have though.
