GBEBZ - I'm close to 80 hours this year alone now ...
Blimey! 80 hours in 6 days is impressive stuff!
Sorry couldn't resist
To echo others I would certainly think about having the odd trip with instructor to keep things tuned and when you want to push your experience boundaries. e.g. when I first went to France I went with an instructor first time out.
When I first qualified my thought process was "why on earth would I want a Pu/t trip having just done 50 of them". With a few more years behind me I would simply see it as the smart thing to do.
