We have Bennett hydraulic tabs on the Ocean (really useful btw....esp for us when lugging lots of water samples about etc.....not always possible to load as evenly as you'd like).
The reservoir does take up a fair bit of space tbh.......no problem with a large 'Ocean' console but could be an issue /def worth taking into account.
If you do go the Hydraulic route, a top tip I was given on here was to use Hydraulic steering fluid in the reservoir.....MUCH quicker to operate
