Hiya,
I would suggest talking to a specialist. Gasman on this site is a hyperbaric doc in Melbourne. PM him for some info so you can make an educated choice between the two. He has been conducting Doppler tests on divers using various deco algorithims and collating data.
We have recently moved away from VPM and to Bulhman with GF. VPM was giving us problems in certain situations.
Can you tell us more about these "certain situations"?
