I started out with some secondhand discs from a friend, and I've bought a few more recently to cobble together what I think is a decent learner's bag. I've only had the mids for a couple of weeks after recommendations to stick with putters and understable mids while learning. This is what I've been throwing.
Aviars
Logics
Stingray
Sol
Mako3
Fuse
Leopard
My consistent distances are all around 150', both backhand and forehand. I can sometimes get an extra 25 feet or so out of my Leopards and the Fuse when throwing backhand, but not consistently. I can get up to 200'-225' with the Leopards throwing forehand, but not consistently yet. Early on I was throwing a Roadrunner, and I'm pretty sure I was able to push that out to 250 a couple of times, but it was pure luck.
Like most newer players, I need to work on everything, so I'm having trouble deciding what to focus on first. It also seems like there are 2 or 3 different philosophies for each type of throw (backhand and forehand), so with so much great material out there, it's been hard to decide which 'teachers' to focus on. So far, I think I like Overthrow Disc Golf and Robbie C, which both seem beginner-friendly.
