Hardie of loaded his Prolite 900 on me as he found it To Technical to ride.
The one I've got has square 90º rails front to back, used to be that grabby in chop it verged on downright dangerous so I filed 5mm chamfers on the rails from the mast track box forwards, this alleviated the board wanting to pitch you in the lumpy stuff.
This was the board which helped me learn how to Gybe better, you either got it 100% right or it spat you of.
It got to the stage where I was afraid of the board, till the fatefull day I dragged it out of the shed to give it a go on Hardies run, first run was great, after a little but of tuning the bard was Furken amazing, the water we have down at Hardies is ideal for this beastie.
I cracked my first +30knot Nm on it in up to knee high chop with a peak of 37knots straight of the beach without any tuning.
I have found "the love"


for my Prolite 900 unfortunately an unnoticed 1inch long hole in the bottom let some water in and i think it may have affected the Cardboard Honeycomb core (yep not foam cored).
I think the 900 is close to 100 litres son yours is probably closer to 90.
I'm well impressed with them for such an old board on Hardies they go like the clappers.
