I play the 699Pro iron, 4-AW with a few customizations to them. Played Titleist irons for a long time and never really thought I would make a change but Sub70 caught my eye after reading a bunch of positive reviews about quality, craftmanship, custom options, etc so I decided to give them a try. Talked with Jason about my game over the course of a couple of conversation and I pulled the trigger. All in for just under $700 compared to about $1700 from other models I was considering.
I could sing the praises of these irons for as long as you would like to listen. Superb quality and craftsmanship, confidence at address, and buttery smooth. They are point and shoot weapons that will make you smile. After one solid range session, went to the course and hit 14 greens in regulation. Please don't ask how many birdies I had but safe to say, it was considerably less than GIR's.
Also play the 849 Pro driver and it is a keeper. If your looking to make a change and want to try something a little different, give Jason and Sub70 a chance to win your business. You won't be disappointed.
