sboardcrazy said..Problem is I lOVE my 95ltre..also when the wind gets over 25kts here there are often big lulls and the 95 will keep going whereas the 78 goes off the plane easier..I hate slogging! Too tiring. I may have to bite the bullet and start using a larger sail on the 78.At the moment the largest I use is the 4.2m which only works with c 25kts +.I only had the 18cm weedie last season.Now I've got a 23cm I will have to force myself to use the 4.8 with the 78ltre board and relearn how to gybe..ugh

If the 78 is a good board you will learn to love it more than the 95.
The 78 is still a big board for you. If the wind is gusty/up and down, learn the right downhaul settings for the 4.2 and 4.8 so they handle well with a big wind range.
I enjoy keeping the board planing in lulls by using the faces of waves, bearing off, trimming the board slightly flatter. Keep the harness line ends close together so you can feel the right sheeting angle for maximum power as you bear off etc.
