I loved mine when I first started. It's good those who can't control their putting. If you blow by the basket and leave yourself with a 20ft+ par shot then this disc is great for you. When it lands it sits....almost no chance of a tourney roll. Hits chances and flops into basket. But when your putting gets good you'll find yourself having much more control with other disc. It's a cool disc to have in the bag and it has it's uses.
I just picked up my Blowfly a couple of months ago and so far its a love hate relationship. I've made some what I consider fairly difficult putts with it and I like the fact it doesn't tend to go too far on a botched putt. I hate it when it slaps the chains and decides to jump out on a fairly routine putt. I think Ill treat it just like any of my other discs...just keep using and practicing with it, and if it starts act'n up...throw it at a tree.
