I think it's a good idea Pete.
the positive is that you can get better trophies for the same cash and it introduces uniformity. i have to admit that i wasn't too chuffed about pos 1-5 at rivi all having the same trophy when Tawd had those nice decanters. If the trophies are bought by the club and the club decides that they want to make a tidy profit.....?
The Negative could be that you could win a lot of the same trophies, sometimes it's nice to get a variation. a perfect example was the dragon trophies Quarry had last year.
