I'm thinking of getting the gc2. Two part question. First is when I intergrate the gc2 with the software, when playing on the TGC or protee red chain, do I have to pre select the club I want to use? Or can I just grab any club and the gc2 will read it? And the second question is when the flash eventually goes out, (30000 to 50000 swings so they say) how much does it cost to replace it. I've heard from 100 to 500 bucks. It doesn't sound to appealing to get the gc2 if I'd have to spend 500 for a new flash every time it needed one. Thanks
