just grabbed some new bearings and wanted to ask how different people
go about removing the grease to lower rolling resistance.

Easy... Remove the seals with a tiny screwdriver then let them soak in a baked bean tin with petrol covering them for several days, give the tin a shake a couple of times a day then blow the rest out with some compessed air.
But remember they will need to be lubricated with something else or they will rust quickly.

Something else you should realize is that the lighter the lubricant is the wear will increase and be the basis of a good Grinding Paste. Personally I wouldn't bother just use INOX regularly and it will penetrate the bearing quickly thinning/diluting the grease, it also helps to flush the bearings. I also use a leather washer which is in contact with the retainer nut and bearing to sweep away sand that might enter the Race.
The more you tamper with bearings the sooner they will wear out. If you are going to be that competitive then be prepared to use a lot of bearings. Mind you if you can pick them up at a Tractor and implement supplies they are only about 7 or 8 bucks.

for my 20mm bearings I use a 6004 2RS.they have a small OD of only 42mm , so roll fairly easily. Ive learnt to put them in , leave them alone and throw them away when they start to make a noise.
after sailing I wash, blow ,then a light spray with CRC/WD40 till next use.
Thats it
