Can anybody tell me if I can buy clubs with my coins only?
WGT does not offer any easy way to gather or view the specs of them however, so renting them and viewing them is the only way to find out whether it is worthwhile.
I used the coin rental sets early on because I waited to unlock clubs at the higher levels that would not require being replaced as quickly as the lower level clubs that will become quickly outdated.
