As a fellow new player I'm in a similar situation except that I've seen the benefits now of moving away from using the drivers as a crutch on the short range shots. The funny thing about disc golf discs is that we fix in our minds that drivers go farther than putters and we let ourselves develop a comfort zone for our bad habits. The fact is that while we might be able to throw the distance drivers further than the mid range discs right now, we're still muscling the shots and we're not generating the spin and speed that is needed to really throw a disc. An intermediate player should be able to throw a Buzzz or a Leopard 250'-300' before even considering picking up the big distance drivers. An aviar putter can easily be thrown 200'-250' by anyone who knows how to throw with some snap and until we realize that the big discs are actually for the pros and that they're hurting us noobs we'll never actually develop good habits.
As for the topic at hand I can say that you should definitely move away from the faster discs as putters since the actual putters do actually offer some advantages which if you are really serious about improving your game you should seek and develop. Find a putter that feels right and just work with it until you start to see the light. I'm still a pretty hard core noob myself but here's a formula that has worked for me:
-Stop doing run-ups
-Disc down to something just faster than a putter
-Search More Snap 2009 on youtube (or look at the sticky on the forum, would link but don't know how yet)
-Focus on achieving a smooth, consistent release from a standstill
I've added almost a hundred feet to my throws and I'm overthrowing most of the baskets at my local par 3 course using a short mid-range disc. I'm getting way more out of my game now and my putter is the best disc I have for putting. Go for consistency and you'll find that a putter will give the most consistency for putting throws. Hope that wasn't over-answering the question
