I must admit I have never been to GW Truro and it will probably be my first call (if just to find a non-GW club), but that being said, the standard of person that goes to GW is not conducive to me playing there. In all the GW stores that I have been to there are several immutable laws:
1. The Aroma (That God-awful smell from over-excited teenagers)
2. The Conversation ("My army can beat anything" "No, my army can beat anything" all while voices are breaking)
3. The Staff (This is hit and miss, some are good, some are bottom feeders. Ask a question and 9/10 you get a wrong answer. And the pushy sales mentality)
4. The Players (This is probably the biggest problem. This is where you will find the Uber competitive WAAC'er in this natural environment)
If these issues could be resolved then I would happily go. The effects of these issues are mitigated or reduced at a clubs. A club is a much better environment to play in, as the more players they keep the better (more terrain, bigger venue, etc.) their club becomes.
I will go to Truro at least once and see what happens, but if anyone is aware of any clubs in this area PLEASE shout out.
