well my big board this summer was an 09 JP prowave 79 which was great at greenhead and gero, but wasnt suited to scabs for me (being unfit and slower on the feet due to injury). I've just swaped it for a 09 tabou pocket 85L this week but i'm yet to try it.
I'm about 75kg (just weighed myself, must have lost a few when i was sick a few weeks ago

) but i was closer to 80 when i was riding the 79.
I really like the 79 or 80L JP radical/pro waves. It has a lot to do with the shaper (richard green) and my style of riding.
I think with the addition of the twinzers this year alot of the singles have been over looked if not totally forgotten. I also think this years pro wave has gotten more hardcore even though it is wider.
Its hard to put my finger on why i like them so much, but the bigger the waves and the harder you push, the better a sailor they make you look. The trick is commitment, just hold on and hit the lip even if ya think its too late and you will often be very surprised.
I had my best session this year up at sunsets in mast high 5.4 weather on the 79. Soo much fun
