I use a DHBH and never though the handle was short. I have encountered short handles before (old Tfight 320).
I use the 18x20 prior version (same frame). I am loving Dunlop Ice at 50 and OGSM at 53. I can go tighter sometimes to 52/54.
Try this if you want an incredible control setup. Lux 4G also works great at the same tension in the mains.
