Yes, LD still is innovating and improving the USFT he designed... and so is Tim in some different ways. Tim is more into the regulated guns now and LD still believes more in the "Simple Simon" tube design that he hand built the first 7 of, and then got them in the hands of some of the top shooters to prove that Americans could build a great/winning Field Target air rifle... and a good number of championships were won with those first 7 air rifles before Tim mortgaged his house and had some parts made to start his USFT business.
I've been competing in AAFTA Field Target since 2008 and over the years, I've seen so many regulator failures during matches that I'm in LD's camp for non regulated tube USFTs.
A well tuned tube USFT can give you just as tight of FPS spread over 40-50 shots as a regulated rig. I've got a few of them I compete with.
That said, LD did use small Ninja regulated bottles when he designed and built 3 AAFTA qualifying pistols for me after a few years of begging. That bottle regulator is set a 850psi to make 12fpe and is also very dependable and has won many matches for me... including a few National Championships.
I think that regulators that have to regulate down from 3,000 or even 4,500 PSI to the desired PSI have a greater chance to fail. I only fill my pistol bottle to 1,800 - 2,000 PSI and still get 60 plus shots from a fill.
Really the key to either design is a well tuned air gun that shoots well at lower pressure around... 900 - 1300 PSI. It's really simple, the air pressure in the tank changes less shot to shot, as the pressure goes down.. So, if it's a regulated gun, there is less stress on regulator, and if it's a tube gun you can have a much bigger sweet spot in the shot curve, if the tune is using lower pressure.
