The more I think about 15/30 min punts it must be a constant rush after getting through the door to leaving. the time spent actually engaged in services has got to be short and hope the WG isn't a clock watcher, surely the whole reason for this hobby is pleasure and feeling satisfied afterwards or am I missing the point, it seems some, take it as a challenge to see how many WGs they can bag competition style,unless it's an addiction and they need the next rapid fix. May be it's just down to personal preference I can see the point if budget is a factor, but again do half and double the quality, I know if you have a longer punt and it's not good that's a crapper,but you know with a hobby like this nothing with WGs is guaranteed and after all it's only cash and a bit of time you've lost,in general IMHO the longer sessions leave me feeling more satisfied , in the final analysis it's case of each to his own and whatever suits you not what others think.
