The 'traditional' approach is to get a bunch of people together (not necessarily pilots) and do the 'big tour' of the Centre, the North, the West etc; get em to kick in and rack up your 30 - 50 additional hours there.
Kinda depends what you see as your aviation future - if you're heading for instructing, spend the bucks doing the instructors course which adds about 50hr to your TT; if you want to go the CHTR route, knock over the ME & CIR for some added hrs, while adding in some quality depth (yeah, I know at 200TT you're not gunna get a gurnsey with a ME CHTR but you gotta start SOMEWHERE), plus you start making a march on the required number of IR renewals (often need 3+ to get a look in).
Do some PVT flights - hire an aeroplane and see some of the country; ENJOY your licence, while still looking to add hours. Do some additional types ratings - taildragger, aeros, formation, pressurisation, floats...... not only added hours, but a damn fine way to spend your airborne time.
