RE: Choosing second board (130-140l range)
You don't have to waterstart on the Go139, trust me, i weigh 90 and i sometimes just can't be bothered to waterstart (or in lightwind just can't) and i can haul my heavy sails right out of the water.
Also in chop, the Go139 rides smoothly in plane. I've sailed it in open seas and in 22 knots on good chop and i never had any difficulties. Only when the swell gets too big and you have to sail sails under 5.5 you're screwed. but that with all big-volume boards.
